Recently Tyler has discovered rockets. That is almost all he talks about these days. He and I have spent many hours watching model rockets on YouTube and looking at how much a model rocket that flies would cost.
The picture posted above is Tyler on the computer designing his own (Apollo) style rocket in Microsoft Word. Note the cone shaped capsule at the top, combined with multiple stages and then the thruster nozzle at the bottom. You might have to zoom the picture in for a better look.
At the bottom is a video clip of Tyler and a balloon/string rocket he made. Although the quality is not the best, watch as is streaks across the living room and into the wall, a total distance of about 20 feet and traveling uphill.
