Best science experiment kits for 6yo?
Looking for Christmas gift ideas. My 6yo is obsessed with doing "experiments" right now but mostly it's just mixing random stuff in the kitchen and hoping something cool happens. I want to actually get him a real kit with structure but not something too babyish. Saw the National Geographic crystal growing kit and the Bozeman Science slime kit - has anyone used either of those? Worth the money or should I look elsewhere?
Beaker Bots or KiwiCo subscription boxes are great because they're monthly and give you variety without huge upfront cost. Keeps the experiment interest going instead of a one-time kit he burns through in a weekend.
