Well I had found this idea on Pinterest site a couple weeks ago and this past weekend we were watching some kids science show on TV and Daniel was in aww of making this, and begged and begged to do it. I had to get all the ingredients so we couldn't do it until today. So here are our results.
All you need is water, oil, food coloring. On the 2nd try we added alka seltzer for it to bubble. I think he was happy with the end product.
