Find or buy a kit of some sort (like a plastic model kit, a craft-making kit, or an electronics kit), get rid of the instructions, and make something that's not at all like the intended result. I picked up a Glitter Pie kit called 'Art studio in a box' (go ahead... check it out. I love how stars follow your cursor!); the included instructions suggested I make a tooth fairy box, little paper house or corsage. Instead, I made this little shooting star with polka dot fabric, sequins and glitter glue. Fun – and i now have a bunch of fun supplies for a future assignment!
