Sam first became aware that you can build your own rocket in Boy Scouts. So when he had a free day with Dad and Grandpa Don, he knew what he wanted to do with it. Build and launch a rocket!
As a newbie to this whole rocket business, I was quite surprised to find out my 10 year old was indeed old enough. All I could think was: “Danger! Danger!” But the men followed the safety procedures, and it really was great entertainment!
The three men explained all the science to me, but in the end I just retained that the wad helps the parachute release and the doodad below the engine forces it up. And the doohickie attaches to an indicator wire deallyhoo that can go bad so you might want an extra thingymajiggy handy just in case.
Wanna feel like you were there? Check out this video montage! (Or skip towards the end to make fun of my freaking out montage.)
