"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!"
"My kids love the unique projects and the variety of choices. We’ve tried STEM, Physics, and Chemistry, and each one has been a hit."
