A fun Pinterest find that both kids loved. Very simple too with ingredients you probably already have in your kitchen. Always a bonus. :)
What you need:
baking soda
food coloring
vinegar
medicine droppers
something to put it all in (we used plastic trays)
Dump a fair amount of baking soda onto a tray.
Drop dots of food coloring onto the baking soda.
(We found that the gel food coloring does not work as well as the liquid)
Fill your medicine dropper with vinegar and drop it onto the food coloring in the soda.
Be amazed.
Repeat.
Repeat.
Repeat.
Watch it fizz!!! Try mixing colors. Try using a little bit of vinegar, then lots of vinegar. Talk about chemical reactions. Figure out how to make orange and aqua. So much fun. They even loved watching it slide off the trays and into the sink - it was really pretty. Bonus: it's good for the sink pipes.
