Hermitically Sealed 2 Year DIY Rotation Globe

We recently saw the MOVA globes reviewed on Veritasium so watched it's inventor's videos on how he invented it then searched some more and found the recommended video below on how to make your own for only a few dollars.

It uses a clock mechanism that you can buy in any craft store for about $10 that will run on a AA battery (instead of solar cells) for 1 to 2 years and maybe longer.

This was our first attempt so it's not absolutely beautiful but has a real nice effect.
We had trouble finding the right size balloons. You need 12 inch round balloons. Our balloons were smaller or not round and only covered enough of the inner 3 inch acrylic sphere to keep it water tight but not to look perfect.

We think of it as a 1RPM compass motor.
