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!

Works and looks as expected, product description should be more specific

There will be a glass protrusion from the cylinder on one end that is not in any of the pictures. After clarification with customer support, the function of this protrusion is that it "lets the air necessary in the tube to allow the hourglass to rise when turned over." This should be listed as part of the product description and pictures.

Once the hourglass rises, it is nearly 2 minutes on the nose. I would had been disappointed if the hourglass was not exact with the timing as why not make it be functional?

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.
