Steve Spangler is a kid at heart. That has to be the reason he was able to design a science kid that truly connected with kids. His kit is designed to hand over the keys to real experiments with rocket science. Our testers got to see what its was like to shoot rockets into the air as well as creating their own rocket fuel! The kit includes everything you need in order to complete this experiment, a launching tube, two canisters and baking soda to make the fuel. Parents appreciated that they also include safety goggles. The directions are very clear and precise. This kit is definitely for older children since it is about being patient and experiencing trial and error as you find the right combination of ingredients to create the best rocket fuel. How do you know? Well, the higher the rocket goes the better your fuel is! Parents were thrilled with the genuine excitement their kids exhibited about doing science projects.
