Steam Simulative Aircraft Turbine Model Engine Science Experiment Teaching GiftFeatures:
.Mechanical Crafts: This is a "unique" steam turbine designed with reference to the principles of steam turbines and aircraft engines, combined with the characteristics of low-pressure and low-speed small boilers.
.Operating Principle of Machine: A machine that converts the kinetic energy of water vapor into the kinetic energy of the rotor. When the machine is running, it will be very shocking and eye-catching, which is impressive.
.Science Educational Toys: This is an interesting and imaginative engine model. You can explore science in the process of playing and observe the magical operation and energy conversion process.
.Well-made: Independent start without assistance, high speed, long life and continuous work. Mainly made of metal, it has a beautiful and atmospheric silver appearance. The surface is finely polished to prevent rust and fading. The texture and beauty are excellent.
.Product Description: Because the steam pressure of the small boiler is much lower than that of the real machine, the impeller structure used in the model is slightly changed. Theoretically, the thermal efficiency of the steam turbine is 35% higher than that of the piston reciprocating steam engine. But because the pressure of small boilers is very low, and the steam turbine is not forced to do work. Therefore, in the low-pressure and low-speed model world, pistons are better than turbines.
.Wide Range of Applications: This is an amazing and wonderful product, suitable as a holiday gift for technology enthusiasts, family, friends, and children. It can be used as a science educational toy to study the working principle of the engine, provide materials for children's science projects, inspire curiosity and creativity, and can also be used as a cool desktop decoration artwork.
.Simulate the principle of aircraft engine, support DIY modified generator

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving.
In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there.
The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.
