In this edition of Everyday Science, host Brian Jones brings students into the studio to learn all about the concept of mixtures. Highlights include: making cornstarch and water goo, panning for gold, scooping the amazing magic sand, pulling real iron out of breakfast cereal, and making glass candy! Brian discusses how mixtures can arise from chemical reactions, mixtures or the building of polymers into long chains. Brian gives viewers recipes for trying many of these experiments at home.

This show was one we informally spoke about as "The Goo Show." Our goal was to do some experiments with mixtures, solutions, reactions and polymers that were pretty gooey... it took us hours to clean up the mess in the studio, but we came away with a pretty cool show!
|Meara checks out a bowl full of "magic sand."
This sand can be put in water, but it doesn't get wet!

In the most gooey segment of all, we made up some cornstarch and water goo that works sort of like quicksand: you can walk on it, if you walk the right way...
If you don't mind making a mess (and who does, really!) there are a lot of cool things you can try at home:
Check out these experiments - and let us know if you find anything cool!
