"Fun experiments each month to do with my daughters. Easy to follow instructions & a great STEM teaching aid. I was a chemistry major so I love being able to show my daughters why I love science."

"Our 7 y/o daughter did her first box immediately and, when she was done, asked when the next one would be delivered! She loves it! It’s high quality and a great addition to our home school science!"
