No school today!

So we're watching Mythbusters today and the kids wanted to know why you can mix powdered jaw breaker with some powdered cleaning agent, add water and heat, and create a big huge fire. Ha! Time to feed the little brains that want to know about chemistry.

So, where to start? Of course we did the vinegar and baking soda thing. They were all very impressed especially when I added too much vinegar and overflowed the bowl. Pebbles was less than pleased though and was all scienced out all too soon.
Anyway, the next one was an expirament that will take longer. The egg in vinegar. And since we were talking about calcium and vinegar together we also tried some calcium tablets as a sort of race.


Our two little cups containing our expiraments.

Here's our egg after about 20 mins. Very pretty.


And here are the calcium tablets! 20 mins and these babies are falling to bits.
