Angry Bird in Liquid Nitrogen : Fun Science Demonstration
Angry Bird in Liquid Nitrogen is a fun science demonstration where kids can make the angry bird more angry by freezing them in liquid nitrogen. Let’s have some fun with the angry birds.This Acitivty can be used in Classroom or Science Fair as Shows.

Images & Step by Step for Instructions for Experiment
Step 1: Using an OHP marker, make eyes and beak on a ping-pong ball.
Step 2:Color your angry bird with a permanent marker.
Step 3:Color the beak of the angry bird with a highlighter.
Step 4: Using an OTP marker, mark two points on your angry bird exactly opposite to each other.
Step 5:Heat the pin of a board pin.
Step 6:Poke the two points in the ping-pong ball using the board pin.
Step 7: Pour some liquid nitrogen into the steel container.
Step 8: Put your poked angry birds into the steel container.
Step 9: Take your angry birds out of the steel container and see it going crazy!!
Working Principle of Angry Birds :
Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. Liquid nitrogen is a cryogenic fluid that can cause rapid freezing on contact. There is 78.09 % Nitrogen present in the atmosphere.
In this experiment, the liquid nitrogen gets inside the holes you made on the Ping pong balls and when you take it out the liquid rapidly converts into gas and escapes from the holes. Now, since it’s a sphere shaped object, there were no edges to balance it out. This is called torque. Torque is a force that causes things to rotate.
Try this out with an object with edges and see what happens to it.
