Amazing chemical reaction between North Korean coin and US quarter



What kind of demonry is this? Our faceless, voiceless, assumedly-hand-modeling demonstrator is able to press one coin through the other without a whole lot of effort.

Luckily their webpage - where the coins are sort of on sale for €35.50 for three coin pairs - says the following about the 'trick':
These coins are made of gallium and indium bearing alloys that when in contact, spontaneously form a non-toxic eutectic (well defined melting point) alloy that is liquid at room temperature!
The above trick, though, seems much quicker and smoother than does the one I've seen before.
