This couldn't be simpler! I bought a bunch of 7/16" ball bearings at the hardware store. They were less than 50¢ each! I took some super glue and glued them together, and that is it.

Making them was filmed in real time and took me under 20 seconds.

This super easy project is a blast to use! I dare say you will get a lot of entertainment from playing with these! I know I already have. Give it a shot, you can have a set ready for tonight!

<p>I super glued 2 marbles together after grinding a small flat on each one, but got a bit nervous after they parted company. I was using the compressor on them to see how fast they'd go, fortunately I had them spinning in a pot lid and the brim saved the day.</p><p>After that incident, which admittedly was my own fault, I decided to solder the ball bearings together. I grind a small flat on each and tin the flats with solder, then squeeze them together while applying heat. So far they've stayed together. </p><p>One can also wrap some thread around the middle and spin them like a top.</p><p>Great fun all the same.</p>
