Jeff Fries - 2008-09-05 How did they get the air in there
dementomstie - 2008-09-05 It was done with an air compressor filling up an empty tank which was also connected to a quick release switch. When the quick release switch is triggered the pump stops filling the tank and at the same time the air from the tank is released from the tank shooting the sawdust into the air.
At least that's how they explained it on Mythbusters.
Rodents of Unusual Size - 2008-09-09 Yes, but can they make a calculator out of sawdust? THAT is the real question.
