Frequently Asked Questions
What kinds of kits does 4M make?
Two main types. The science side covers crystal growing, hydraulic arms, propeller racers, micro rocket launchers, and robot-building kits. The craft side includes friendship bracelet kits, chalk factory sets, rub art studios, and glow-in-the-dark room decor. Most kits include everything needed to complete the project.
What age range are 4M kits for?
Most are designed for ages 5 to 8 on the craft side and 8 and up on the science and engineering side. The Chalk Factory and Tooth Fairy Box work well for younger kids, while the Hydraulic Arm and Propeller Racer are better suited for older builders who can follow multi-step instructions.
What is the 4M Crystal Growing Kit?
A kit that lets kids grow real crystals from a chemical solution over several days. You mix the powder with hot water, pour it into the mold, and watch the crystals form. The assortment comes in multiple colors and each finished crystal can be displayed on the included base.
Are 4M kits good for classrooms and gifts?
Yes. They're self-contained with clear instructions, so they work well as independent projects. Price points range from $6.99 for smaller items like glow-in-the-dark sets up to $29.99 for the larger builds, which makes them easy to match to a gift budget.
