What should i do for my science fair project
A good idea of a science fair project is using beverages as cleaning agents. You can use Coca-Cola for instance and come up with cleaning agents to remove hard stains like grease and tar.
Test the properties of matter
It depends if you actually have to do an experiment, last year I did a science project on optical illusions which was very interesting
