Low Temperature Differential Stirling Engine Model Science Experiment Educational Toy - GoldenFeatures:
.Low-temperature Differential Stirling Engine: The LTD Stirling Engine is novel and unique, with integral base and bracket flywheel. This model engine is an excellent Boutique model
.Fine Workmanship: Constructed with stainless alloy and zinc alloy, durable to use. The assembly precision of each part is high and it is smooth to run. The metal surface is treated by electroplating process, which can improve the features of wear resistance and corrosion resistance and enhance the combination of beauty, texture and aesthetic feeling
.How to use: The product has been assembled and ready for operation. Place the LTD Stirling engine model over a cup of hot water, preheat it for 30 seconds around, and turn the flywheel on by hand and the engine will continue to run
.Stirling's Principle: It's an engine that operates in a low temperature differential environment. Reversible cycle consisting of two constant volume heat absorption processes and two stable expansion processes. There are four processes: constant temperature compression process, constant volume heat recovery process, constant humidity expansion process, and constant volume heat storage process
.Educational Toy: Through the operation of Stirling engine, you can observe the operation process, thus more intuitive understanding of Stirling engine structure and principle. At the same time, due to its superior quality and beautiful appearance, it can also be used as a technological decoration, and can also be as a gift to friends and relatives or children

Quality product but sold on Amazon cheaper with different seller.
Size: Medium Size 2, Color: White-Blue
The size is the reason for the missing star. Made of good quality but found cheaper from another buyer. My 9month Cane Corso hasn't destroyed it yet and enjoys playing keep away with the other dogs.

absolutely must buy perfect for dogs. I have a large black lab and he has had so much fun with us.
Size: Large Size 3, Color: White-Blue
I have to say that my dog would be considered an aggressive tower. However, this ball has stayed intact. I love that it comes with the pump. It’s extremely functional very soft for catching can be cleaned. Very easy easy the quality is exceptional. Very functional does have a bounce. I can say he has had so much fun with this since it’s getting it for his birthday on 11/11 I highly recommend this product and would definitely buy again.

Perfect for keep-away
Size: Large Size 3, Color: Red-Blue
I purchased one of these for my pup and he has a ball throwing it up in the air and chasing it. Handy for something they can play with alone.

Great durable ball
One of my dog’s favorite toy. We have had this ball for almost a year and it is still intact. My Doberman loves it and has not been able to destroy it. The size is comparable to s tenis ball. It has a little weight to it witch makes it easy to trow further.

Best toy I’ve ever gotten for my dog
The toy allows you to interact with your dog in a way that I didn’t realize was so important until I adopted a dog who was ball obsessed and a bit disconnected. We have bonded so much over this toy and it has held up so much better than 95% of the toys I’ve gotten, which have all been labeled as high-quality or durable. It is perfect for playing fetch and for tugging, as well as training.
The only thing worth noting is that the rope is thin enough that it can be uncomfortable to tug with a large or strong dog. I usually wrap a leash around my hip and hook it to the rope when we are doing intense tugging (because my 75 pound dog would win otherwise).
If you do go for a tug toy that has a more comfortable handle, it will not bounce and be easy for a dog to run around with in the same way. This rope makes the weight heavily in favor of the ball, so it acts more like a ball and the dog is more inclined to grab the ball.
I think this toy finds right balance of ball to rope.
