Shrinking paper money with ammonia

Support Applied Science on Patreon: https://www.patreon.com/AppliedScience

As a follow-up to my previous video on bending wood, I show how ammonia can shrink paper money.  The money is dipped into liquid anhydrous ammonia, then dried, and the process is repeated about a dozen times.  As the money dries, it shrinks due to the surface tension of the boiling/evaporating ammonia.

Extreme wood bending with ammonia

Bending wood with ammonia is not really DIY, but I show the process, which is extremely effective.  There is also a commercial product that is pre-treated flexible wood, which hardens after being clamped in the desired shape.

Hmm, it seems the product may no longer be available -- I can't find it at Inventables.
