Variation on an existing theme: a helium filled backpack, which you strap on, to go jump around.
It won't lift you, because it contains only a few kilos of lift (say 25kgs), just enough to make your body a serious bit lighter to give you the 'moonwalk' feeling.
The underside of the pack is strengthened
by a strip of rubber, so that your tail can touch the ground without the pack getting damaged.
Mainly designed because I like the form of the object (see pic). Nothing special, just yellow and kangaroo-ish.
Quickie, the form is pleasant I think
http://i3.photobuck...esel/heliumjump.jpg Been designing so many things with this form, cell-phone, cocktail shakers, macaroni, etc... the line isn't perfect here, but you see where it's going [django, Sep 06 2006]

Lookie! Giant flying bananas! |

Not be used indoors, I presume. Or do I presume too much? |

A backpack? To get this much lift would require about 900 cubic feet of helium. |

Well, let's divide the volume up into spheres: in the middle a sphere with a radius of 2 metres (=33.5 cubic metres), on top and under it, one with a radius of 1.5 metres (=two times 14 cubic metres: 28m³); and two small spheres of 0.5 metres radius at the extremities (=two times 0.5m³ = 1m³). In total we would have around 62.5 cubic metres. |

One cubic meter of helium gives around 1 kilogram of lift, so you would have 62.5 kilos of lift. The total surface area would be somewhere around 90 square metres. Now take a strong hypalon fabric weighing 0.3 kilo per m² and your fabric weighs 30 kilos.
62.5 kilos of lift, minus 30 kilos of fabric = 32.5 kilos of net lift! |

That should give you anti-gravity feelings. And all your worries about having a heavy bvtt would be gone instantly! |

I already have anti-gravity feelings - horrible heavy stuff that it is. |

Don't let go of product or hand it to small children. (+) |

Love the illustration and the idea. |

This sounded like something the Clusterballoon guy might have done, though not so prettily. He had a link to Parabounce, which crashes my computer. I googled, and got a lot of hits, but haven't looked at any. |

The tail could act as a spring. |

Smurfs! That's it, now I remember where I've seen that form before. I grew up with Les Schtroumpfs, that's it!! Has been lingering deep in the depth of my genius mind for decades! |

Not to be used in high... or any... winds. I
could see a bunch of people jumping
around like nutters in a tall warehouse
with a padded floor. [+] |

A padded ceiling would be more useful I think. |
