Query: wastey science

Please don't waste your money on this product. It's beyond ironic that the word "tasty" is in the title, the stuff is not even edible. Most of the experiments use home ingredients, the kit has 4 test tubes and a couple of packets of "ingredients" and 3 horrible "flavors". The suggested experiments aren't worth the mess they make and the dishes you have to do afterwards. The only thing my 6 year old learned is that sugar tastes pretty good as long as you dont add their flavoring.
