If you ever had a toy microscope as a kid, you'll probably find this neat: EyeClops is like a handheld microscope that plugs into a TV - it will magnify 200 times and display the image right on the TV screen.
Plus it looks like a cross between a giant eyeball and a squirt gun! Not badly priced, around $50. http://www.amazon.com/gp/product/B000PGRBGA?ie=UTF8&tag=starwarscust-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=B000PGRBGA - Thanks John!
