More Rocket Fun!
Googling around and I found a terrific rocket simulator/design tool at NASA!

This amazing thing does simple ballistic, water, and solid engine rockets. Even better - it does AIR ROCKETS! (pictured). This will come in handy! (I'm planning on having some fun this weekend launching air rockets at a family gathering.)

Wow - Rocket-palooza!
I had a blast launching 4 different Estes rockets at the field with some neighbor kids for their Science club (really). And they got to launch the air-rockets dozens and dozens of times - great fun!

TOO LONG since a posting. But here's a new one: AIR ROCKETS!!!
http://www.sciencetoymaker.org/airRocket/index.html
I'm going to show off model rockets for some neighbor kids this week, and I built one of these to show off - almost free rockets that you can blast off.
I tested it indoors (big mistake) then had to work to clean the smudge off the ceiling. These are more powerful and fast than you'd expect. Out doors it disappeared (almost) higher than the trees. After two launches it was lost in the trees. No matter - a little paper and tape and I've got two more ready for flight.
