Ants have an almost legendary ability to carry loads far in excess
of
their own body weight. Moreover, the wealth of ant-fossils in
amber
prove that the ant's exoskeleton is relatively easy to glue things
to.
I contend, therefore, that it should be possible to glue a sufficient
number
of ants to the soles of a pair of shoes to support the
weight
of a human being.
Were this to be done, and if said shoe-wearer were armed with a
walking stick tipped with a suitable ant pheromone, it would be
possible to achieve an eerie, smooth and sedate mode of personal
transportation.
Initial experimants have, it is true, not been encouraging
(particularly for the ants). However, there are many thousants of
and species out there, and the search continues. As in anterim
measure, MaxCo is working on its Personal Trantsport Platform
which, being about a metre square, distributes the load of the
incumbent person more benignly across a larger number of ants.

True. But, if you're out for a nice sedate stroll, what could
be more pleasant than to find yourself drawn to a picnic? |
|
| |
If we assume ants can carry 25 times their own bodyweight, which is... ( harder to find out than their size! Let's assume it's 5g) then we'd need around 10000 to hold up the weight of light flyweight boxer (50kg). |
|
| |
If we guesstimate that small ants are around 5mm long and 1mm wide... and that our light flyweight is a UK foot size 7 (260mm long and possibly 80mm wide)... then we have about 52 by 80 ants (4160). |
|
| |
Perhaps our boxer could wear clown shoes or skis.
{By the way, I think I've been overly generous to our ants here.} |
|
| |
The five-gram ants we tried were the devil's own to work
with. But boy were they fast. |
|
| |
Er - I've just noticed the utter nonsense in my anno... hold on while I edit... |
|
| |
Ah - sod it. I'll just put it here. If the ant was 5g, then it could carry 125g - which is *mental*!! I was trying to be generous, and it turns out I was super-generous because then we'd only need 400 ants. |
|
| |
Better is a 1g ant that can carry 5 times it's own weight... leaving the result of above valid. |
|
| |
But don't ants march, not walk, which would give you
a more bouncy walk than normal? |
|
| |
It could be jaunty, to be sure. We've looked into the
jaunting quite carefully. |
|
| |
25:1 .... that'll be how many pounds of ants ? |
|
| |
The 25:1 figure is based on voluntary load-bearing by ants.
Under the circumstances, I think they'd try a bit harder. |
|
| |
If you pound on the ants, you will probably crush them. |
|
| |
Based on the previosu assumption that an ant can carry 25 times its own body weight, and assuming a 150 kg passenger (we're talking fat Americans here), that's 75 kg per lower limb. Divide by 25 and get 3kg. |
|
| |
All you need is to breed ants weighing 3 kg and strap one to each foot, like rollerblades. |
|
| |
Very sneaky... "Moreover, the wealth of ant-fossils in amber prove that the ant's exoskeleton is relatively easy to glue things to" Just go over that bit, again for me?
|
|
| |
I think, what you need here is some form of farm...perhaps even an Alien farm |
|
| |
Teflon-coated ants would not get stuck in the pine resin in
the first place. Of course, this means that entire genera of
Teflon-coated ants may have existed in the past,
unbeknownst to us. |
|
| |
Also, I, for one, weigh somewhat more than 25 ants! ...
Hang on, what type of ant are we talking about? European or East African? |
|
| |
The term "Ant Shoes" does not mean "One Ant, Two Shoes".
The word "Ant" is used in the phylonomic subjugative
recursive sense, meaning "Many many ants". |
|
| |
Well, if you want to travel using ants, best to choose a European species, as it is well known that the African ones are non-migratory. |
|
| |
Perhaps the shoes could simulate the sound of a horse, by having extra ants employed to bang coconut shells together ? |
|
| |
"largest insect is ... the larval stage of the goliath beetle, Goliathus goliatus, the top size of which is at least 115 g and 11.5 cm." |
|
| |
So, that's only about a factor of 25 from the target size. It's a challenge, sure, but it's not impossible. |
|
| |
//If we assume ants [...] bodyweight [..] is... 5g |
|
| |
If we guesstimate that small ants are around 5mm long and 1mm wide// |
|
| |
...then the density of an ant is 1 gram per cubic millimetre, or 1 kg/cm^3. |
|
| |
This is a bit less than 100 times the density of lead, at 11.34 g/cm^3 (from Wikipedia). |
|
| |
Do you really think an ant weighs 5 grams? Weigh out 5 grams of e.g. flour, and take a look at it. Does it look ant-sized? |
|
| |
I'd be surprised if an ant weighed 500ug. |
|
| |
Depends on the ant. <link> |
|
| |
Big, yes, but not quite big enough ... |
|
| |
"Representatives of the extinct dragonfly-like order Protodonata such as the Carboniferous Meganeura monyi and the Permian Meganeuropsis permiana are the largest insect species ever known. These creatures had a wingspan of some 75 cm and a body weight of over 450 g, making them about the size of a crow." |
|
| |
There may be a reductio-ad-absurdum paradox here. The larger a creature is, the more structural strength it uses just to support the "dead load" of its own weight. Hence, elephant bones are, proportinately, thicker than mouse bones (we will return to the vital topic of elephan knees later). |
|
| |
So maybe what is needed here is not bigger ants, but many trained and highly organised dust mites. This would give the advantage of a smoother ride. Also, if rather than supporting the load on their backs, they lay on their back feet-uppermost and moved the user on their feet, on a sort of conveyor system, this would allow them to rest on a 50% duty cycle as once the load had traversed on, they would then scuttle forwards to resume their inverted position ahead of the upcoming shoe. This would allow them opportunities for rest and refreshment. |
|
| |
Does anyone here have any experience of training dust mites ? |
|
| |
What is the collective noun for dust mites ? |
|
| |
To answer your last question first, the collective noun for
dust mites is "a pheme of dust mites" (indeed, it's the same
for all mites). |
|
| |
Anyway, yes, smaller creatures are basically the way forward. |
|
| |
//Good reason not to use dung beetles//
I wouldn't be so quick as to dismiss that: rollerskates, a little "eau de eww" spray on the wheels... |
|
| |
[Wrongfellow]: I did say I was being super generous:
The 5g is most definitely an over-estimate, even for the largest of ants, probably an order of magnitude. Also, the 25 times is a gross over-estimate - at absolute best, this is the maximum relative weight that an ant could drag, using the mandibles. The dimensions for breadth and length are for quite small ants (which would not be the same as the ones allegedly weighing 5g). |
|
| |
First, let's go with the 25x bodymass number. I mean, we're
not giving these guys the option to be slack. |
|
| |
Second assume an ant to be a cube with a density of 1. If
needs be, we can squish them a bit to make them cubier. |
|
| |
Now, assume an ant 1mm on a side. Its mass will be 1mg,
and it will be able to lift 25mg. 100 such ants will fit on a
square centimetre, giving you a lifting capacity of 2.5g per
square centimetre. |
|
| |
Now, assume an ant 1cm on a side. Its mass will be 1g, and
it will be able to lift 25g. 1 such ant will fit on a square
centimetre, giving you a lifting capacity of 25g per square
centimetre. |
|
| |
In other words, the supportable load is directly
proportional to the size of the {cubical} ant. |
|
| |
So, clearly, [MaxwellBuchanan] was talking bollocks when
he agreed with the notion that smaller insects were they
way forward. |
|
| |
How big an ant (in the plural sense) would we actually
need? Well, assume a human weighs 80kg and has a
combined footprint of 500 square centimetres. This
means that the loading is 160grams per square centimetre. |
|
| |
Bearing in mind the foregoing conclusion regarding
proportionality, this means that we are going to need
cubical ants with a side of about 6.4cm. |
|
| |
Now, I agree, this is on the large side for an ant. It also
depends on some dubious assumptions regarding ant
scaleability. |
|
| |
However, our R&D department is amongst the most
determined in the world. Even as we speak, they are
chainsawing their way through the tropical jungles of the
world, seeking ants which meet our stringent requirement. |
|
| |
As a contingency plan, we are also actively developing
methods which will enable more modest ants to carry
greater loads. These efforts involve the fabrication of sets
of six ant-wearable shoes, each of which bears, on its sole,
an adherent layer of millipedes. |
|
| |
As a child I never hesitated to step on a swarming colony of ants, and never despite their species or my lightness of youth, felt in any way lifted or propelled by the acidic muck that was revealed when my foot was later raised. |
|
| |
That, [rcarty] is either because you're a fat bastard (and I
mean that in a chummy British way), or because the ants
lacked the presence of mind to array themselves regularly
and densely beneath your incoming sole. |
|
| |
Also, might I point out that a layer of glue, penetrating to
some extent the gaps between the ants, will provide some
resistance to lateral spreadage of individual ants? |
|
| |

|
| |
I remember being taught in school that ants could carry 200 times their own body weight.
See what you did? Now if I don't find out I won't be able to sleep. |
|
| |
You might not want to piss of the insects...they out number us. So how about just applying the pheromones to the bottom of an average pair of shoes making them think that their queen has been un-earthed and that they must return her home. Now you just have to make them think that home is the direction you choose...no crazy glue needed. |
|
| |
<later> Turns out they can lift 50 times their weight but they can carry at least 100 times their weight suspended. [link] |
|
| |
How important is it that the chosen steeds be ants?
If the internet is to be believed, an adult Hercules Beetle weighs in the region of 20g and can carry up to 850x its own weight.
This puts their load capacity in the region of 17kg, or to put it another way (according to the WHO), a child aged 4 years 4 months of average weight.
Presumably this means that a pair of Big Bad Beetle Bootees would support a child up to the age of around 8, by which time their feet would likely be large enough to accomodate more beetles. |
|
| |
//You might not want to piss of the insects...// |
|
| |
That's what Bill Bailey says... {linky} |
|
| |
How about pair of shoes that have ants inside that bite and sting the feet of the wearer and the objective is to run around long enough so that they are killed in order to stop their painful inducements. |
|
| |
Excellent idea. The flaw is not in the amount of ants required to carry someone, but that they'll only be able to carry you across perfectly smooth, flat floors - any bumps in the floor will result in your whole bodyweight resting on one or two ants, with resulting ant carnage. A more workable mode of transport might be snowshoes, each with a dozen puppies humanely, and in accordance with animal welfare legislation, attached to the underside. |
|
| |
Animals underfoot has been hb'ed before [link]. |

Hush puppies! These are supposed to be sneakers. |

I've strategically positioned myself as a student against the oncoming forces of work. I determine the times and places of engagement with the enemy, utilizing the cunning tactics of sleep and procrastination before smashing it asunder into small and manageable pieces of pen and pencil fodder. |

Education's a wonderful thing, [rcarty]. |
|
| |
Maybe you should try iy. You never know, you might even like it. |
|
| |
Thank you for reminding me of a childhood nightmare of mine about a square meter sized transportation spider. It was actually more of a square shaped flat millipede with legs all around that you stood upon. In this case, you might do better with a skateboard-like object with vibrating, flexible cilia underneath that are angled opposite the direction of propulsion (the idea shamelessly stolen from the HexBug nano -- see link) |
|
| |
It's not *that* new. I remember as a kid seeing (probably at a
friend's house) a game that had a road layout on a board,
with barriers alongside the road. Little cars placed on the
board would magically glide around the roads. The cars had
angled bristles on their undersides, and the board was
vibrated by a motor. |
|
| |
Ah, well, if you were educated, you would know that ... |
|
| |
Hmm. [zeno]'s link leads to an interesting web page, in
which we find: |
|
| |
"If you disagree with anything here, be aware that I also
disagree with a lot of things." |
|
| |
I think this is a useful phrase. |
|
| |
// I think this is a useful phrase. // |
|
| |
"I need your clothes, boots and your motorcycle." is a 'useful phrase' but not one you want to hear used in your favourite drinking establishment.... |
|
| |
Au contraire. Since I have neither boots nor a motorcycle,
and since the most exciting thing to happen in The Spraint
in the last 8 years was the mistaken delivery of packets of
pistachios instead of salted peanuts, I'd rather welcome such
a diversion. |
|
| |
Had the Terminator gone to the right type of bar he wouldn't have met with so much resistance. ("Your clothes, give them to me!") |
|
| |
Maybe they'll do a Perminator remake after Arnold's support of the same sex marriage proposition. |
|
| |
[bigsleep], are you suggesting that K9 was just that? (i.e. canine) |
|
| |
With the application of radiation, ants can grow to huge size without any diminution of their remarkable abilities. This was documented in "Them." |
|
| |
And in the English re-make, "They." |
|
| |
And the Russian "We" (Yevgeny Zamyatin wrote the
screenplay, I believe). |
|
| |
And the subsequent stage comedy adaptation, "Charley's Ant". |
|
| |
Not to mention the musical version "Ant Misbehaving" |
|
| |
Or that one about the zealous ant-killers...
"Pride, Ant Prejudice." |
|
| |
Maybe it's "Legs come looking for you" - the avenging angel (or large angry grasshopper?) happens to be called Legs, due to his penchant for kicking folk? |
|
| |
(Grasshoppers are associated with ants, aren't they? - fables, preparing for winter, etc.) |
|
| |
I have the perfect ant for the job <link> |
|
| |
These things are *almost* indestructible. |
|
| |
You should thank whatever god of your choice you have yet to
encounter fire ants. I hate them. I hate them. I hate them. THEY
, it seems, hate orange oil. I have employed it liberally. But, he
rain. They got my one year old daughter 3 times on the hand
before I realized what happened. In my own house. Orange oil
or not. I hate those ants |
|
| |
Just don't let your ant-matter get too close to your regular matter, or you'll have a big 'splosion. |
|
| |
Would be much more fun if you just went where the ants wanted to go, probably to the nearest food. |
|
| |
One issue that seems to have been overlooked in all this is the question of who is going to do the glueing and how long will it take? What is the average life expectancy of an ant anyway? Will you end up with the first ants dying of old age before the last ant has been glued onto the shoe?
Also, Jinbish's 5g ants must be enormous. Possibly about the same size as the ones that appeared in 'Them' (nods to ldischler). I'm not sure I'd want the job of glueing them to someone's shoe. [Conveniently ignores the fact that Jin has subsequently hit them with a Shrink-o-Ray!] |
|
| |
I'm not sure ants are into pheremones. I think if you just squirted formic acid ahead of them, possibly using water pistols, they would hurry forward. Have you discussed your idea with E.O. Wilson? |
|
| |
I was about to say "No, because he's dead", but he insists he's
not, and has photographic evidence to prove it. I find that
very enheartening. |
|
| |
Perhaps a pair of heel-mounted magnifying glasses? |
