Awesome Thing Of The Day: Liquid Nitrogen & 1500 Ping Pong Balls; Plus, Walking On Water - For Real
September 27, 2012

Now, this is the kind of teacher we wish we had in school.

Dr. Roy Lowry - an associate professor in the Faculty of Science and Technology at Plymouth University in the UK.

For this experiment, he has a canister of liquid nitrogen (ie: liquified gas) and an empty one litre plastic bottle.

Now, if you're not really into science, we should tell you liquid nitrogen is extremely cold; it boils at −196°C.

Lowry and his assistants pour a bucket of warm water into a garbage can. Then, he pours the liquid nitrogen into the bottle and screws the cap on tight, causing the nitrogen to expand.

Next, the bottle goes into the garbage can. And to top it off, they quickly dump 1500 ping pong balls into the can because as Lowry puts it: "we thought it would be quite nice."

Watch what happens. It's pretty awesome.

Another guy who does these kind of experiments is Steve Spangler.

He's the founder of That's a company that designs science toys and entertaining classroom science demonstrations.

You might remember him for his Mentos and diet Coke geyser experiment that went viral on YouTube several years ago.

Well, watch what happens when he was on 'Ellen' and filled a small pool of water with 2,500 pounds of corn starch.
