LOW INVENTORY - ONCE GONE, GONE FOR GOOD

Newton's Gravity Glass is a sand-filled hourglass suspended in a liquid-filled glass cylinder.

Measures 5 minutes of time with either blue, yellow, or purple color liquid. A perfect corporate gift!

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

8" tall

Hourglass inside the cylinder is a 5 minute timer.

I bought the hour glass and really like the purple color. I haven't seen a gravity timer before. I thought the inside hour glass would rise slower than it does but it still functions great and is fun to watch. Shipping was quick.

Unique!

Timer was given as a gift and recipients loved it! Blue color quite attractive. They had never seen a gravity timer before.

Service was prompt and packaging was perfect no damage in transit.

Love the Gravity Time!!!

The 5 Minute Newton Gravity Timer I orginally received had evidently cracked so water was in the sand. I returned it and received a replacement which is great! I can't wait to give it to my sister who saves hourglasses. This will be a unique addition to her collection.

Thank you again.

Replacement was received most likely quickly. I was away for three weeks and just returned home last night. I opened my mail today and the timer is in perfect shape!! Thanks again.
