Animate your fidget spinners like never before with these Running Motion Fidget Spinners.

Blurry to the naked eye, these spinners come alive when you film them on your phone in the sun.

Why can’t the naked eye see the animation? The refresh frame rate of our eyes is too high! We can’t see the frozen picture.

Why does it not always work in video? This depends on the number of frames per second that you’re filming the video in. If you’ve got your video set at 30 frames per second, the spinner must rotate at a multiple of 30 revolutions per second to freeze the frame.

Why do you have to be in the sun to make an animation? When there isn’t enough light there is a smear effect because the light is too fast and the camera shutter is not fast enough. When the spinner rotates at a high speed, we must have enough light to take a freeze-frame picture so that the shutter of the mobile phone can automatically meet the high shutter speed and freeze every frame of the rotation.

Not suitable for under 5 years.
