how can i build an ornithopter(rubber band powered) without a kit?
have a physics project…and can it be built without balsa wood????it isn’t available in stores here…also please give ideas for a physics project based on mechanics only….
a trebuchet is easy to build and is mechanics only.
there really isn’t much of an alternative to balsa other than styrofoam, but maybe you can try popsicle sticks?
check your local hardware store and ask them. Also call a carpenter and they might know where you could get some balsa.
