Physics teaching tool, executive desk diversion, and meditation aide. The Newtons cradle, or Newtons "pendulum", has been a classic in the science-themed toys department for years. It was invented by British actor Simon Prebble in the late 60s, and named in honor of Sir Isaac Newton's third law of motion. The novelty "toy" demonstrates that for every action, there is an equal and opposite reaction. The fact that the resulting demonstration, and the rhythmic sound it produces has a calming and relaxing effect, has made Newton's cradles popular desktop devices. If you're looking to take action and buy a Newtons cradle, we've got some options we hope you'll have a good reaction to...
Coffled Newtons cradle
The time-honored design keeps this traditional
We've chosen a traditional design as our top choice because you really can't improve on the beautiful simplicity of a classic Newtons cradle. This is a high-quality product from Coffled. The base is made from Dutch wood, the spheres from 304 stainless steel, and the cables are strong nylon lines. It measures in at 7.7-inches tall and 4.7-inches wide, so is the perfect size to fit on your desk. Coffled boasts up to 20 seconds of movement, depending on how hard you strike the balls, and how many you set in motion.
ScienceGeek kinetic art asteroid
Go beyond pendulums with this stellar choice
ScienceGeek has taken the perpetual motion concept in a space-themed direction with this planetary option. A truly mesmerising choice, this is an attractive objet even if you don't consider the interesting physics demonstration. It is battery-powered to create an electro-magnetic force to repel the battery attached to the spheres. This gives it an extra scientific angle to make it an even better teaching tool. Despite its complicated looks, this is actually very quick and simple to set up.
Faxadella Holocradle Newtons cradle
Rainbow sparkle makes for an even more engaging experience
Made by Faxadella in Philadelphia, Pennsylvania, this is an interesting twist on the classic Newtons cradle. Anyone who is interested in purchasing a Newtons cradle for the relaxing effects that watching one has should consider the Holocradle. This is because the spheres and base are made with glittery, iridescent, "holographic" materials. When in sunlight, or under bright white light, this results in a mini rainbow light display every time you set the balls in action.
MarsGeek Newtons cradle fridge magnet
Add some physics to your fridge with this playful choice
Add to your collection of geeky refrigerator magnets with this super-fun, fridge-friendly Newtons cradle. This product from MarsGeek has three strong magnets on the back of it so it can safely be attached to fridge doors, lockers, metal filing cabinets, and more. The five pendulums have an attractive shiny, metallic finish, and the cables are a strong wire. It's the perfect kitchen distraction to keep you occupied while you're waiting for the microwave to ping.
Bojin 7-ball Newtons cradle
A larger scale option for even more physics fun
This larger option has no less than seven spheres to max out your Newtons cradle experience. The entire thing has a very elegant chrome finish with clean, curved lines, making for a sophisticated desk accessory. Although this has more spheres than alternative models, it's still relatively compact, measuring 4.5-inches high and just under seven inches wide, meaning it won't take up too much space. The frame and balls are made of stainless steel, and the cables are made from nylon.
Bits and Pieces LED Newtons Cradle
The illuminated spheres add extra interest
The classic Newtons cradle has been given a high-tech makeover by Bits and Pieces as the company has refreshed the design by adding color-changing LED balls. This is powered by six AA batteries (not included) which make the LEDs light up and change modes from blinking to cascading, and back again. This cradle has a high impact plastic frame. As far as size goes, this illuminated option's base measures in at 6-inches by 7-inches and it stands 8-inches high.
For every action...
Our overall top pick in the collection, the Coffled Newtons cradle, is a very traditional design, honoring the original invention created over 50 years ago. It's testament to Newtons cradles how this simple design has endured, and remained popular for so many years.
If you are looking to shake things up, then there are alternatives that bring a different twist to the classic design. The Faxadella Holocradle Newtons cradle for example, is made from "holographic" materials that means every time you set the pendulums in motion you get to experience a mini rainbow light show.
Another option we love is the MarsGeek Newtons cradle fridge magnet. As well as holding any notes, lists, photos, or pictures in place on your fridge door, this novelty item offers a geeky way to keep yourself entertained in the kitchen. Just don't get too distracted and forget why you were headed to the fridge in the first place...
