School Science Projects

It’s for my kids science project

Me and my buddy, Percilla, are doing a science project. We are testing different chemical substances and we were wondering what chemical you would get after melting said bands. Help?

this is for a kids science project we used four kinds of salt, epsom, sea salt, kosher salt, regular salt to see which would form a bigger crystal, our results were sea salt made the biggest crystal. How do i explain why?

what kind of propellant is the best (shoots the furthest) and what is the cheapest one that works? Pretty much its any kind of aerosol spray that is flammable. Where can i get them and how much does it cost?
I’m not some crazy kid its a science project for school on which one will launch the potato the furthest.
Thanks in advance
