Circuit Cubes were designed to make toys move, light up, and create noise in new ways. Attaching a battery and motor to a predesigned car from IKEA is one fun way to give your old toys new things to do.


1  Gather a wooden IKEA car, a roll of Scotch tape, and a rubber band

2  Assemble a Battery Cube, a Motor Cube, and a LEGO wheel in one place

3  Align the Motor Cube with the wheel

4  Slide the wheel onto the Motor Cube

5  Stack the Motor Cube ontop of the Battery Cube, ensuring the metal posts are at opposite ends

6  Take a piece of tape and make it into a loop. Stick it onto the bottom of the Battery Cube
TIP: This tape loop is what will secure your Cubes to the car, so be sure it’s sticky and secure!

7  Upend the Cubes onto the back of the IKEA car, pressing firmly to adhere. Now you're ready to drive!
