LiquiFly Fizz 火箭發射器

Third launch in a row went straight up maybe fifteen feet, and the kids were already mixing the next batch of vinegar before it even landed. The snap-together base holds firm on grass, so no chasing the launcher across the yard. Best six bucks I've spent on backyard science this summer.

We were all outside watching the rocket soar on the first launch, and the bicarb and vinegar reaction is so simple even my 7-year-old could load it alone. Definitely buying more colors to run races.

My kids couldn't stop giggling as the rocket shot up with a satisfying fizz. The simple bicarb and vinegar reaction is so easy to set up, and the colored rocket adds a nice surprise.
