2 Minute Newton Gravity Timer

GWS032-1

Continue Shopping or Checkout

The Newton gravity glass is an awesome desk-topper and a question-generating educational tool. When the cylinder is flipped, the sand within the hourglass moves down while the hourglass itself floats up.

The hourglass inside the cylinder measures 2 minutes of time with either blue, magenta, or purple color sand. A perfect corporate gift!

It's all good

The two (2) 2-Minute Newton Gravity Timers I purchased both look good and work as expected. The staff was also helpful.

Very nice !

An unusual version of the 2 min. hour glass. It works differently than you might expect. Makes a fun desk top addition.

Nice but not what was expected

When I ordered I was under the impression that the hourglass inside the liquid would take 2 minutes to go from the bottom of the tube to the top of the tube when the timer was flipped.

This is the behavior I had seen in another Gravity Timer. Therefore I was very disappointed in the product. Just having an hourglass inside liquid is not fascinating. As I result I did not give it as intended as a gift to my grandson.



** UPDATE from JustHourglasses: Based on this customer's feedback we have clarified the description of the product.

I did receive the product quickly and in good shape.
