2.   White styrophone
3.  Paper  
4.   Bread
5.   4x Test tubes

Steps:

1. Have your ingredients in strips  (banana strips, styrophone strips, paper strips and bread strips)
2.   Grab your test tubes and rack, put a piece of banana and the rest of the strips in the test tubes
3. Add half a test tube of water to the bread only!
