Features:


.What's  Ringbom Stirling Engine?
Ringbom engine is a unique Gamma-type engine. the displacer of a Ringbom Stirling is not driven by a mechanical linkage, but by gas pressure variations forces on a displacer piston rod within the engine because the piston is connected to a crankshaft. The Ringbom Stirling cycle engine is unique in that there is no mechanical connection to the displacer.  The engine has only four moving parts.
The Ringbom engine concept published in 1907 has no rotary mechanism or linkage for the displacer. Ringbom engines and the plans are very rare but now you can build a Ringbom engine of your own!

Science & Educational Toy:

create an educational and entertaining model with Stirling principle, innovative design and rigorous craftsmanship. Stirling engine is an amazing external combustion engine with low noise, low pollution and low operation costs, while capable of running powerfully and fastly just by heating the engine with an alcohol lamp.  


.Power generation by science & technology: the whole working process of the engine can be observed in a bright place. Not only can the engine run at high speed but also it is able to light the bulb. You will be captivated by the light and feel the magical process of energy transformation when the engine is working in the dark.


.Exquisite manufacturing: the main body of the engine is made of zinc alloy material in electroplating workmanship, with rich metallic luster and enhanced industrial texture. Features 4 anti-skid pads at the bottom of the model for smooth operation.  
.Multiple Usages:

the principle of this closed cycle reciprocating engine is the gas compress and expand periodically at different temperatures by external heating. The easy-to-use engine is excellent for physical/mechanical demonstration, classroom teaching, scientific experiments, display, desktop decor, etc.
.Perfect Gift: this is an interesting and imaginative artwork for visual and aesthetic enjoyment, making it suitable for children, teachers, students and technology enthusiasts. The engine is a perfect gift for family and friends on Christmas and birthdays.

zelda‘s “indoor” ⚽️ ball!
Color: Squeaky Green, Size: Medium Size 2 (6")
zelda loves her soccer ball - because of the fabric “tabs”, and the way she treats her toys, we keep it inside. she loves to place all of her toys and bones on our bed, after they’ve been cleaned. this ball is perfect and soft enough to throw it down our steps, where she will run down, retrieve it, and bring it back to the bed. it arrives deflated and comes with the pump and two needles - the pump is not the sturdiest and felt like it was not inflating, but after only having to reflate it once with a bit of air since receiving it ~5-6 months ago, it still holds up!

Small for a medium
Color: Red-Blue, Size: Medium Size 2 (6"), Color: Red-Blue, Size: Medium Size 2 (6")
I got medium.. and it does not look like a medium ball.. it’s rather small. It’s pretty sturdy and my dogs went crazy for it but it’s definitely not the size I thought it was going to be 😂 my dogs chewed one strap within 5 minutes of having it but they’re dogs and that’s what they do lol. I bought this to be an outside ball for them! It’s pretty light but that’s probably because it’s small. Not soft? But feels like a soccer ball. It also had no smell coming out of the box. Also comes with a pump and an extra thing to put in the ball to pump in case you lose one. I like these balls, I expect them to be chewed up because that’s what I bought them for! Fun for my dogs and they are! But the size… it is not medium and that’s the only reason for 3 stars 😂😂😂 Other then that I recommend, your dog will definitely love this! Inside or outside playing! Alone or with another dog!

Great toy for a GSD
Color: Blue Gray, Size: Extra Large Size 5 (9")
My GSD loves to grab the flaps and shake her head with the ball bouncing of the side of her head. This is her favorite toy. I thought she would puncture it but it has held up great since she likes to grab the flaps rather than biting the ball.

Pup loves this!
Size: 6 Inch, Color: Red
This soccer ball is so cute. My dog loves to play with these. The straps are durable, easy to pump up (they come with a pump), good value for the money since they tend to last awhile, at least for us. The straps are durable but could be an issue if your dog is an aggressive chewer. They stay pumped up for quite awhile and just need to be topped off once in awhile to keep the bounce there. We keep them outside even in the winter and they do just fine. HIghly recommend as a good play toy.

Great Ball
Size: 6 Inch, Color: Red
Our Little Goldendoodle Loves this ball & I like that it has so many straps to grab so I'm not getting the slimy part. It does not come already inflated so make sure you or a neighbor have an air compressor to blow it up because even though it came with a little pump I can't imagine how many weeks I'd have been pumping that without noticing any difference.
