Technology has improved our use of movement to do work. This includes robots, drones, and remote-control toys. But the basic principles behind movement require no batteries or cords! From making floating pepper flakes dance to building a hot‑air balloon out of a plastic bag, explore movement using household items and a little bit of science in these fun science-based activities. Step-by-step instructions and photos guide readers through each activity and Science Takeaway sidebars explain the science behind the results. All projects use common materials found around the house.
