LEGO Chain Reactions is packed full of ideas, instructions, and inspiration for 10 LEGO machines that spin, swing, pivot, roll, lift, and drop. Each machine alone is awesome, but put them together and you get incredible chain reactions. Then, combine the machines in any order you like to create your own chain reactions. Our team of experts worked with educators and 11-year-olds to invent the machines, then wrote a book that teaches the skills (and some of the physics behind the fun) kids need to create their own amazing chain reaction machines.Our book includes 33 special LEGO elements that co...

1. Introduction This is a simple permanent magnet DC motor model to demonstrate the DC electric motor working principle. It can be taken apart and reassembled, when powered with 3-6V voltage (some clients may use 12V battery to test it, that is not advocated). It will rotate like a real electric motor ideal for school scientific projects or physics teaching. 2. Cautions: ① DC motor experiment: input 3V - 6V DC through wires and terminals, the coil will rotating, and speed up when voltage step up. ② To avoid short circuit, two electric brush never touch the commutator segment. ③ Permanent...

If you live in a region that typically experiences high temperatures but low humidity, consider harnessing the power of evaporative cooling to make indoor/outdoor living more comfortable for your family. Evaporative coolers — affectionately known as swamp coolers — work by passing water through a 3D cooling pad and using a fan to dry hot air across the soaked pad to cool it. This all-natural process relies on physics instead of freon and other chemicals, so you get affordable, comfortable climate control that comes with a reduced carbon footprint. Air flow capacity 500 cfm
