Here’s a challenge for you. Make the coolest thing you can from a bucket of old golf balls. It might be hard to beat this Sierpinski triangle and Sierpinski tetrahedron!

These are both made by Dale Seymour. And in case you are wondering if is is solid golf balls all the way through, here is a picture of Dale gluing them together:

Send me a photo if you make something cool (or post it to the MAKE Flickr pool and leave a comment/link below).
