On Friday at clubs we had Mrs Raj instead of Mrs Adcock because Mrs Adcock was away for a Manaiakalani meeting. Popcorn is irreversible which means once it has been made into popcorn it can not turn back to the seeds. Popcorn pops when the heat goes into them because there is water in them so when the heat goes into them the water can not hold the hot air out so it finally gives up and pops. There are three kinds of molecules in liquids.

1. A tight tight molecule
2. A loose molecule 
3. A loose loose molecule 

 We ate popcorn afterward.
