A Victorian Halloween: Flexible Giant costume patterns and plans


…build and operate a mechanical device to simulate, remarkably well, what happens when a robotic spacecraft takes advantage of a “gravity assist” on its interplanetary trajectory through the solar system. The device substitutes a strong, moving magnet for a massive orbiting planet, and a steel bearing ball (BB) for a spacecraft. The “magnetic assist” it provides to the BB is closely analogous to the “gravity assist” a spacecraft can receive from a planet moving in its solar orbit. Link.


These dolls are blank and come with markers so your kids (or anyone else) can draw their own designs, faces and more on them. They’re $40 which isn’t too bad, but I bet you could get a doll pattern and make your own DIY Draw-It-On Dolls. Could be fun for kid’s parties and such. My version might have a LCD as a head and you could draw on that… [via] Link.
