This week the physics of sparklers, custom 3D printed cars (for the road), and you don’t have to travel to a galaxy far far away – hoverbike technology is here.

Hoverbikes are real:  The United States Army Research, Development and Engineering Command has commissioned two companies to develop hoverbike technology. Malloy Aeronautics earlier this month demoed a working hoverbike at the Paris Air Show.

Customize your own 3D Printed Car: The new car is an EV and Local Motors hopes that the car will be able to be 3D printed on demand and it is intended to allow the customer to add custom colors and trim pieces to the car.

The Physics of Sparklers:  It depends on the kind of sparkler, but the temperature of these sparks can be anywhere from 1800°F to 3000°F (1000°C – 1600°C).
