Details

This Newton's Cradle demonstrates the conservation of momentum on a 6" x 7" red wood base with it's 6.25" arms 4.375" away from one another. The 5" string length provides a pendulum length of 4.496" to the 4.3g nickel plated stainless steel balls each 0.876" in diameter.

Overall, the unit weighs in at 1.65lbs and is a perfect gift anyone who is nerdy, into science, geeky, or just generally awesome. It also looks pretty good on anyone's desk.

It comes disassembled, and while it's pretty easy to put together, you must very careful and delicate while assembling it. The strings can warp easily and will make the cradle out of alignment.

Make sure you read the instructions though and wait to remove the styrofoam until after the uprights are screwed into place. Putting it together incorrectly can lead to string warping which will ruin your lovely Newton's Cradle. Seriously, we would be really sad if you did that. You probably would be too.

  • Nickel plated stainless steel balls with 4.3g of mass
  • 7.25" Overall Height, 6" x 7" red wood base
  • Comes partially disassembled and requires CAREFUL assembly
  • Note, do NOT remove the styrofoam protection from the balls until you have screwed the uprights into the base

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
