Tech Will Save Us' new kits let kids harness electromagnetic energy

In the lead-up to Christmas, the STEM toys are coming thick and fast -- we've seen everything from DIY computers to robotic arms and Lego trains for pre-schoolers. Enter Tech Will Save Us (TWSU) with two new kits that teach kids to learn to play with electromagnetic wireless power and conductive thread (setting them apart from other STEM gear). Moving beyond the larger-than-life Marvel superheroes and mounds of dough TWSU is known for, the focus here is on demystifying resistors and capacitors by incorporating them into accessories that light up everyday objects. The "Light Racer" kit, for instance, lets kids build their own bicycle wheel LED lights in the shape of kick-ass lightning bolts straight out of Asgard. The tykes will have to wrap their heads around coils, emitters and capacitors to understand how to generate stronger power and brighter light.
