We homeschool and it was the perfect science project and great instructions that my child could follow on his own.

My goal these days is anything I can do to get my daughter off screens is a big hit. We had a good hour and a half full focus on this. BIG hit. The slime was the draw but the surprise at the circuit was the ultimate winner.

While our 7 yr old could follow some directions - he still needed some help decoding: the BEST part was all the experimenting : grapes, corn cobs, water, glycerine soap!!!! We wished the battery lasted longer!!!
