After trying and failing to make our own baking soda / vinegar rocket based on online tutorials, I decides to give the kit a try. It was an instant hit, with our family at home and with a large group of kids at our space camp coop. Make sure to have a lot of vinegar and baking soda on hand, because you'll want to do it over and over again! After at least 20 launches, it is showing its wear. I'd probably prefer a more sturdy version with less assembly, but overall, this was huge science fun.
