If you have trouble deciding what to do with your day then the Dynamometer is just the machine for you. Similar to our Pneumatic Engine, this model operates by turning air pressure into motion. The difference is that this model will give direction to your otherwise aimless day. Blow on the top gear to set the mechanism in motion. The air pressure you apply spins the arrow until it lands on your task for the day. Now get to it!

    5 out of 5 Incredible!

    Made this over the weekend with my family, was a great product, challenging but fun, and made having three heads to figure it out worthwhile. Since, we’ve had lots of comments from guests, and immediately ordered the pneumatic engine model!

    Great job!
