Best! science experiment edible gift
The 12-year old boy ( my boyfriends' son)is learning to cook/bake and enjoys it. He loves science experiments too. So for him to start making his own food items is a huge plus because it's empowering to make something you cam eat. And he LOVES the root beer flavor.

Excellent Gift
I bought this for an adult engineer as a gift and he loved it! It's a fun, whimsical gift that is perfect for the analytical mind who wants a light break. Very fun.
