STEM gifts are loved by kids and parents alike, and this Gumball Rally is set to make some big moves during the holiday season. Not only can it be reconfigured and reused to create all sorts of obstacles, but it also comes with edible gumballs to be enjoyed as snacks along the way. Silver loves this option for a STEM pick. This science kit is great for introducing kids to physics concepts in a hands-on way. Building and solving requires creative thinking, and after your machine is built you can eat the gumballs once youre done sending them through.
