  1. Thank you for this post! My five year old wants to be a scientist when he grows up, so we do a lot of science experiments in our house. I love the rainclouds, goop, and constellations.

    1. Yes! So many times I’ve wanted to do fun stuff like this but the project requires such specialized ingredients. I love that I have most of the items required for these experiments already in my cupboards!

  2. This list is outstanding!! I love the rain clouds and the walking rainbow! It’s my daughter’s birthday this week and we may have to try these with her friends!

    1. I love that it’s a super inexpensive activity, you can just grab a couple cans of shaving cream from the dollar store! Have fun with the birthday celebrations!
