Think we are going to have to try this :)
What's the surface you're using in this photo?
I poured a box of baking soda onto an old cookie sheet. :)
What a great idea :)
Soooo much more fun than just vinegar and baking soda. Mind if I add to my boys' craft site? Thanks. http://www.squidoo.com/workshop/crafts-for-boys
@TravisAnn Sherman - feel free. :)
This is fantastic. I love that it's chemistry and colour mixing all in one. We gave it a go and I posted about it with a link back here on http://a-little-crafty.blogspot.com.au/2012/07/soda-and-vinegar-colours.html
Thanks! This kepy my boys happy for an hour too - and they made aliens to walk on the 'moon' :)
