Features:
- A selection of high-quality materials, the body is made of brass and stainless steel, the performance is superior, firm and strong. The quartz heating tube can be operated at high speed for a long time without wear.
- Finer Workermanship: Most of the whole machine is hand-polished and the base is manually polished by CNC machining. The surface of the product is smooth and bright, emitting golden and silver light, which is not easy to rust and fade, achieving a dual combination of texture and beauty.
- How to operation: During operation, the engine model is placed in a horizontal position, and alcohol is injected into the alcohol lamp to ensure the safety of the alcohol lamp, the alcohol lamp heats the piston tube, and the dry air expands to generate power, which drives the two flywheels to rotate rapidly and illuminates two LED small lamps.
- Educational Value: By operating the engine, children would observe and know the operational process and more intuitive understanding of the operating principle of stirling engine, deepening their interest in physics.
- Wide Application: It has a wide range of application as, great gift for Kids' science project, Physical/mechanical learning, teacherâ€s Demo props on the class, birthday gift for friends, families, parents, kids, etc.

Chuckit medium rebound balls
Size: Medium
My 8 month old German shepherd dog loves these balls. They are easy to throw, they bounce great, they are very chewable! She keeps one in her mouth most of the time. It satisfies her need to chew and she does not chew other things. She drops it in the water and lets the hole fill up and drinks that way. The only problem that has caused is suction in her mouth and difficulty in dislodging it for her. However, she would be lost without it!

These are definitely indestructible
Size: Medium
Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.
