Experimenting with a led strip

In about a month, I will be in a primary school to do some light painting with the children. I'm going to do this together with Ton. I have bought some cheap USB-powered led strips and power banks, with the goal of creating some sticks the children can wave around while the lights are changing colours. This shot is a test where the led strip was stationary and I moved the camera. The effect of doing it the other way around should be the same... Next step: get some plywood to create the stick to attach the strip and the power bank to.
