A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work.

Teachers can make the explaining process much more straightforward and students can better understand its principle.
Run freely on the top of a cup of hot water, no need to fire an alcohol lamp, safer for children.

The start temperature difference between the product bottom contact and circumstance shoulder be greater than 25℃.
Gently flip the wheel, then it can run itself.

Not for us!
Size: Large, Color: Antler
I'm sure for a dog that doesn't chew, would be great. Ours went through it in days, leaving sharp shards and making his gums bleed.

Great for tough chewers!
Color: carrot orange
This is awesome for my 85# Labrador. He is very destructive with toys and this has held up great. After months of playing with it, only teeth marks on it. Worth every penny. The green top crinkles which my dog loves.

My dog was obsessed with these
Color: carrot orange
Bought these for my dog and they were an instant hit. The carrot shape is cute, but more importantly they kept my dog entertained for quite a while. The squeaker still works and the toy has held up better than I expected considering how rough my dog can be with toys. I always expect squeaky toys to be destroyed within a day or two, but these have lasted surprisingly well. They're lightweight, easy for my dog to carry around, and have become one of the toys that gets picked out of the basket the most. If your dog enjoys squeaky toys, these are definitely worth a try.

Good one.
Color: carrot orange
Our Lab loved it. Nice and sturdy apart from the leaves, which were short lived. Overall a good toy for a big boy.

Fun for retrieving and chewing.
Color: carrot orange
My lab loves this carrot, and uses it to retrieve and is not easily destroyed. However, he was able to pull off the leaves the first day. It’s still functional, just know they’re gonna come off if you have a chewer. Purchased based of recommendations for indestructible toys.
