Make your own DIY overhead projector for tracing wall murals. Make a makeshift projector using a box, a lamp and some tape. Project the transparency onto the wall. Use a light bulb without the "frosting" on the inside for a clearer picture.
Draw on wax paper with permanent markers, wrap around candle and heat until image is transferred. It would be great to do this for Mother's Day, or Teacher Appreciation Day - have kids draw on wax paper and give her a personalized candle.
