Imagine It! - Sept. 9, 2017 - Barrel Bender

TOLEDO (WTVG) -- Here's the hypothesis: Air pressure can be adjusted by using extreme fluctuations in temperature.

You can see what happens when the Chief Scientist at The Imagination Station, Carl Nelson, adds water to a barrel and rapidly heats it using a propane-fuel torch.

Then, he seals the barrel and rapidly cools its contents with an ice bath.

Watch the principles of air pressure illustrated in this scientific experiment that has implosive results.
