Experiment 1: Making A Banger!
What you need: sheet of stiff paper measuring 16x12 inches
Fold the longer edges of the paper together 
Then open it back up
Fold the four corners into the first fold
Fold the paper in half along the first fold
Then fold it in half again, lengthways
Open out the second fold
Fold down the two sharp corners.
Fold the paper back along the second
fold to make a triange shape
Flick it down quickly - and a flap of paper
springs out and makes the air move suddenly.
You hear this as a loud "BANG"!
Hey I really liked this. I showed B, and he wouldn't put it down. He made loud noises! He said he is going to bring you the paper that he uses, and it will make an even louder pop. If we can deal with all of the "pops" this would be a great experiment to do in science. :) <3
