Pause Your Shadow
This is a cool looking toy the “Shadow Magic Kit”, it actually pauses your shadow whilst you keep moving.
To use it you need to hang the supplied Phosphorescent screen on a door or wall, get an over energetic child to jump up and down in front of it whilst you take a snapshot with the supplied light gun thingie and voila a static image of the shadow is now on the screen. You also get a light pen which lets you doodle with the shadow.
This is the sort of gadget I can see keeping kids entertained for ages and it only costs $25 from Discovery Shopping a bargain IMO.
