I am going to show you how to make your own plastic in this instructable.
You will need: Milk,Water,White Vinegar,Bowl,Egg Beater,Spoon,Knife(Optional),Baking tin,
The long milk molecules will overlap along with the diluted vinegar. Then, a rubbery substance will be created. Later, the rubbery substance will harden into plastic.
Step 1: Mixing and Heating
Mix all your ingredients together, then heat the milk up till it is hot. (Not boiling or frothing though!)Make sure to mix the vinegar and the water, then mix the milk along with it.
