5 Best Perpetual Motion Toys for Fun in 2018


What’s not to love about perpetual motion toys?

In fact, chances are high that you had something of the sort when you were much younger. But it’s ok if you didn’t.

For starters, ‘perpetual motion’ best describes the fact that the repeated movement of these toys provide never-ending hours of real entertainment (even though we know that in some cases, ‘never-ending’ can only happen when you have a good supply of a certain form of energy).

Nonetheless, isn’t it rather surprising that at first blush even the best perpetual motion toys seem like they’ll bore the geekiest of people to their teeth? Really, who hears of a toy that explains science and readily jumps on it?

Quite a few; if you ask us.

However, in spite of the simplicity of toys like cosmos perpetual motion toys, perpetual motion toys offer a wide range of fun-filled opportunities for you to demonstrate and teach scientific principles.

Moreover, the fact that they are toys doesn’t place a limit on how old a user should be to use them. The whole family can join in an entertaining and educative fun time.

Talk about a family bond growing stronger!

Without further ado, let’s show you 5 amazing perpetual motion toys that we think you’ll fall head over heels in love with.

1.Toysmith Euler’s Disk

[amazon box=”B000239E6Q” template=”vertical”]

The Euler’s Desk by Toysmith is a must-have for anyone who would like to explore the fun and thrills of perpetual motion desk toys. This toy is a hypnotic ball of sound and light.

It comprises a 9-inch concave round mirror base, 9 strips of beautiful holographic foil, and a patented 3-inch disk to attach the foils to.

We particularly love the fact that this toy explores the principles of magnetism with the magnetic properties of the holographic foil.

Here’s how it works: the disk which has the attached foil is spun on the mirror base. And as the spinning progresses, the mirror reflects the image of the holographic foil – creating a hypnotic but beautiful display of light and entertaining sound.

Need we tell you that the fun gets better as the disk spins faster? Well, it does. In fact, the sound gets louder with some more spinning.

What’s more? Learning just got more interesting and fun-filled because this toy comes with scientific answers and instructions. We are almost certain you will love this magnetic perpetual motion toy as much as we do. Psst! You are not too old to have this toy in your home or workspace.

Or would you like to try the Toysmith 3-D Mirascope? This toy is a million shades of cool. It makes a 3-D holographic projection of small objects among other creative displays.


  • Comes with instructions and some scientific answers.
  • Explains and uses a wide range of concepts in physics.
  • Creates a hypnotic and beautiful light display and some sound.

4.Sunnytech Hot Air Stirling Engine Motor

[amazon box=”B07B8G7FB3″ template=”vertical”]

The Sunnytech Stirling Engine Motor will make a great gift for kids and teens. If you are out of ideas on what to get a child, student, or loved one this season, look no further than this perpetual motion toy. It will also come in handy if you are a science teacher and will like some teaching aid for your next class.

The Stirling Engine works differently from an internal combustion engine. This explains why it is referred to as an external combustion engine. It comes fully assembled with an extra LED light and gas cylinder. All you need is about 90% alcohol solution to fuel the engine and keep the light on. You should be able to get alcohol from a local store near you.

Once you follow the instructions correctly, then you get the chance to own an engine that runs madly on its own. This toy is known to make customers happy. And because we want you to join the happy train, we think you should go for it.

But if you prefer something else, you can try the CMS Magnetic Levitating Desk Toy . This enchanting toy has a multi-colored shell that makes it more visible when it spins.


  • Suitable for teaching purposes
  • Great gift for older kids and teens.
  • Made from high-quality materials.

It explains the principles of how external combustion engines run.


  • We would have loved it even more if the edges of the flywheel were rounded and not sharp.

5.The Famous Drinking Bird

[amazon box=”B000JSGLBK” template=”vertical”]

The Famous Drinking Bird doesn’t chirp or flap its swing. It actually does much more than a bird will do. For starters, this fascinating toy works on many principles of physics to create fun-filled moments.

Oh, yeah, we know he isn’t so fantastic with the looks but “fine” can’t make a boring day better, don’t you think?

So, how does it work?

First of all, the drinking bird is pretty much a heat engine. It functions on thermodynamic laws and constantly bobs up and down as a result of the difference in temperature between the head and bottom. The head is kept cooler as the moisture in the bird evaporates.

Over time, the top of the head becomes heavy – causing the bird to bend forward. This, in turn, sends a rush of pressure to the head so that the fluid is forced back to the bottom. At this stage, the bottom is heavier and the cycle goes all over again.

We love the fact that this bird actually keeps working for a while even if doesn’t have a glass to drink from. As long as the felt in its head is wet you can be sure it will keep working; except it becomes really dry. In such cases, you can just wet the head.

We have a few concerns though. The fact that it is made of glass means it is safer for kids to watch it rather than handle it. Also, the fluid in it leaves permanent stains on most surfaces. To avoid this, we advise you to place the drinking bird on a tray and fill the tray with an absorbent material.

Would you like something else? Check out the KINGZER Top Totem . This fascinating spinning ball comes with a die and a branded carrying bag.


  • It is a suitable educational toy for kids and teenagers
  • It is a pleasure to watch as the bird keeps drinking.
  • It works perfectly well even when there’s no water to drink from.

It is easy to set up and keep running.


Kids must be closely monitored around this toy because it is quite fragile.

How to Choose a Perpetual Motion Toy

There are almost no two perpetual motion toys with the same features. This means there are a million and one options to make a choice from. This is why we took it upon ourselves to do the dirty job of finding the diamonds in the rubble. We hope you loved them.

Meanwhile, here are some important factors to consider before you make a decision:

Aesthetic value:

Among many reasons why people buy perpetual motion toys, one of them is design. Some people are particular about the toy’s design for aesthetic reasons. If you are big on how objects sit in your space and the elegance they add to your existing theme, then you should zero in on design before you make a choice.


 a Perpetual Motion Toy

Some perpetual motion toys combine a number of scientific laws and principles to create an impressive array of never-ending motions. So, if your sole purpose of getting one is to teach the kids some principles, then you should go for a toy that closely matches the concepts you want to teach.


The more sophisticated a perpetual motion toy is, the pricier it is. Elaborate designs also mean some more bucks. This is why it is very important that you have a working budget before you shop for a perpetual motion toy.


Heads up! You should never compromise on quality or you’ll regret every single cent you spend. You should look out for the part, material, and comments from those who already have the toy that you want. It is a safe way to ensure that you don’t get inferior quality.


You should also check out the safety of the toy. Most manufacturers spell out safety precautions while some others don’t. It’s your job to find out.

For instance, the glass material of the famous drinking bird is a safety hazard especially when you have kids around.

*drum roll…*

Our top pick is none other than the Sunnytech Weightlifter Kinetic Art Balance Toy. It was an easy pick for us because of its aesthetic value, educational benefit and simplistic design. We also love the fact that it is safe for kids.
