Connect ruler stabilizer fins with 2 rubber bands.
NOTE: Why you need stabilizer fins: Without fins, prop and bottle both spin in opposite directions. With stabilizing fins, the prop spins and the bottle moves forward.
What happens when you take a comic book artist, an inventor, and a toy designer? You get Howtoons. Our mission is to provide engaging content that teaches kids how to build things, combining instructions with storytelling. Howtoons has a foundation of science and engineering education, inspiring creativity through art and imagination.
The primary contributors to Howtoons are Nick Dragotta(comic artist), Saul Griffith(inventor), Ingrid Dragotta(toy designer), and Joost Bonsen(the big kid).
