How can we use Nitrogen ? • Prevents things from reacting with oxygen • Fills some tires. • Liquid nitrogen can be used to freeze things.

Important!!! • It is poisonous. • So, while experimenting we should be careful.

EXPERIMENT TIME!!! “Explosion Of Ping Pong Balls with Liquid Nitrogen. ”

First Step • You should wear your glasses, your glasses and any other materials that will keep you safe for your safety. • Thanks for attention
