There is a box with a highly explosive bomb inside it. The lid of the box is made of glass and attached to this lid is a bowl of mercury with a dozen exposed wire leads just out of reach of the mercury. You know that any attempt to remove the lid or cut through it would move the mercury enough to trip the bomb. How do you safely disarm this booby trap to disengage the bomb?

How about freezing it, wouldn't that also work. Not that i know a great deal about Mercury.

If U Breath The Fumes You Would Die so You Are Taking a Big Risk!

the problem with freezing the mercury, although it would probably work, is that you'd have to somehow get the temp down to -38F or -39C (mercury's freezing point). unless you happen to have a little liquid nitrogen on hand... =)

How about using a straw or large syringe to just suck the mercury out of the bowl, and avoid all the dangers?

I thought the mercury would expand first, before it evapourates touching the wires?? I thought freezing would be a better solution, because the volume of mercury will decrease giving you more room to work with. Even only down to 0 degrees C, you would have more room to work with. Whats wrong with having liquid Nitrogen anyway? It is a situation.

Shryke, that would stille be VERY, VERY, VERY dangerous. Mercury is a deadly substance and getting any in your body is a very BIG risk. You should never ever put mercury on your body and especially in your mouth!

couldn't the bomb not be lit?

mercury is used in regular thermometers because its volumic expansion is greater than that of average materials (ie glass and steel) and thats why it can give accurate temperature readings of such a scale... obviously, it would need such a high temp t evaporate it, it would expand a LOT before hand

why can't we spill the mercury?

I had thought of that early on, but I questioned the fact of what the explosive is.I unfortunately made the assumption that the highly explosive bomb was highly sensitive to heat.

Besides that, great teaser!
