Train drivers used to hit train wheels with a hammer before setting off and were able to judge by the noise whether the wheel was cracked. This small USB-powered device will gently tap your biscuit and feed the sound into an analysis package to determine the biscuit's structural integrity as a safety
measure before any planned dunking goes ahead.
Avoid biscuit-based injury

A nice cup of tea and a sit down.

I think [hippo] would like this place. And the accompanying book which is my personal reference for all things biscuit related. [wagster, Sep 08 2009]

It has to be non-destructive testing. The energy input shouldn't be sufficient to cause an incipient flaw to propagate. |
|

Ultrasound pulses might be better. |

wheel tappers and shunters - would there be a shunting device whatever that is? |
|

This could, in another world, where hippo's double is a man of unlimited animus and limited social skills, have been an altogether simpler device, for serruptitious use in supermarkets and tea rooms. |
|
| |
Perhaps for tracle biscuits, there are syruptitious uses? |

Ohh yeah. Another goody that got by me. I hear this
as a tiny ting sound. Like the one before one
meditates. On a good biscuit day that is. |

//Train drivers used to hit train wheels with a hammer //
Telephone linesmen are also trained to hit telephone poles with a hammer to judge if they're safe to climb.
If they "ring" they're dry and safe; if there's a dullness, they're rotten.
My Grandad knew this, but used to drive his GPO van into them instead.
If they fell over, they weren't safe to climb in the first place. |

re: link. Interesting research, copro, but deeply flawed Ifeel. A noticeable absentee from the list of risks associated with the deadly combination of tea & biscuits is, of course, polonium poisoning. This makes the whole provenance of the report extremely suspect as I know, from personal experience, that the streets of London are littered with the bodies of ex-pat Russians who have not exercised the appropriate caution during their tea breaks. |

I (based on just about nothing) expect that a biscuit would
attenuate the sound too much for it to be usable. Perhaps
phase-contrast X-ray imaging instead, or terahertz? Actually,
come to think of it, heat flow imaging would work pretty
well, and be easier and cheaper than both of those and
safer than X-ray. And you've got a heat source handy. |

*Whack*
- no, sorry, this one's cracked
*Whack*
- huh, this one too.
*Whack*
- ah ... nope.
*Whack*
- sorry, no joy.
- Did you only have four left? Insufficient redundancy, I'm afraid.
- Could I have that tea if you're not using it? |

I am shocked to find that this essential item is not yet
available in selected stores. |
