Suction Fire Type Stirling Engine Model Hot Air Stirling ModelFeatures:
.Improved Design: The engine with side inlet is improved. The brass cylinder is durable and long lasting. Brass bracket and brass flywheel (similar products on the market are made of aluminum without surface treatment, which will be black over time) to make the whole machine shiny gold, and look high end. The core parts are brass and stainless steel, the materials are exquisite and the structure is simple
.Stable Performance: Aluminum alloy bottom plate and plexiglass double bottom plate solves the problem of deformation of the previous heated bottom plate, giving consideration to both appearance and durability. Through technical improvement, the Stirling model has better start-up performance and stability, and is easy to maintain
.Parameter: Flywheel diameter is 65mm. The length of air cylinder is 50mm. Diameter of cylinder is 22mm. Piston stroke is 26mm. Speed range is 100-400r/min
.Fuel: 95% alcohol should be used in the operation (not included), not water, kerosene, gasoline, lighter oil, liquor.
.How to Start and warm up: Put the engine model, then light the alcohol lamp. Adjust the position of the flame and turn the flywheel to warm up. The position of the nozzle will condense droplets of water, and if the flywheel is swiveled, it's going to create resistance as the piston expands. When you keep spinning the flywheel for a minute or two, the drag will decrease, and then the flywheel will start working flexibly. Speed up after 3 minutes. Run for 10 to 15 minutes and blow out the seedlings to cool the model
.Meaning and Value: By operating the engine, you would observe and know the operational process and more intuitive understanding of the operating principle of stirling engine, deepening your interest in physics; Its superior quality and exquisite appearance also make it of high collection value, which can be used as high-end decorations or gifts. Suitable for people over 14 years old. The product has been assembled and can be used directly
.Warm Tips: Be careful not to get hot during operation. Do not clean engine at high temperature

Frustrating but crazy fun
Color: blue, Color: blue
Maybe it’s just me and my breed of dogs but I bought 4 and within 30 seconds of placing them all down on the floor at the same time, we were down to 3… I have 3 German shepherds and a mastiff… 1 shepherd licked once and then took the whole thing in her mouth and ran out the doggy door…( if you own a German shepherd I hope this message finds you) it’s been an hour and I still can’t find the new bowl…so now we are down to 3… I blended some wet dog food and mixed with Greek yogurt for one… texture was smooth but the ball wouldn’t move fast enough for said shepherd so after some adjusting of the consistency… I still couldn’t figure it out…so as one pup is licking one ball, I grabbed the pumpkin puree and yogurt and it was still too thick… so I watered it down with a little bit of Vienna sausage juice…which now of course the crew is waiting for Vienna sausages to be dispersed among this group of terrorists….and as I’m dispersing, I noticed the bowl of wet dog food was upside down and the pumpkin puree bowl was on its side leaking orange liquid out the top… I’m still working on consistency for the remaining bowl… (mind you, we have already had breakfast which consisted of sausages from the oven as we love beer brats for breakfast… 3 cans of wet dog food that all the babies line up for and are spoon fed -and a couple pieces of cheese as I was prepping dinner) ok so now I have a runnier consistency with adding that sausage juice…got it to where I could move the ball pretty easily but then once again it got too dry and the ball just kept getting licked and nothing was sticking to it…when taking the device apart, I noticed that the liquid has no problems being licked up but the problem is that the thicker product gets stuck on the sides and the ball can’t pick it up for some reason… it needs to be nectar consistency or thinner for my family…as I’m seeing… during this whole time I’m mixing different consistencies on my counter… holding on to one with my foot as they do not stand up against large breed mouths, slide all over and also trying to make sure they stayed safe in the home as these were not the cheapest…and holding one in my hand for my special needs shepherd…these things were slipping all over the floor. They are heavy and feel durable but someone back me up here… I have learned so much about my breed of the GSDs… but my life has changed so much since having these babies because learning what can stand up to these dogs is a daily-no-HOURLY TASK. My dogs do not find enrichment activities fun. They bore easily and that’s probably my fault… so when I saw these enrichment bowls I was pumped!! The treat mats, (were shredded within minutes of realizing we couldn’t get treats out quickly) the boxes with the *whack-a-mole” cheese stick games…the poor Amazon box that I so carefully cut holes into did NOT see my shepherds mouth coming… these special toys that the dogs have to roll around to release a treat… no. No. No. I’m still finding chunks of THAT poor toy… these should not be called ‘slow feeder dog bowls’ liquid treats yes but the videos of the dog owners making the yummy stuff to go inside need to be a little more specific… as we all know, all dogs are different… but this product was supposed to entertain the puppers for a little bit but 24 hour supervision is required in this home which is not ideal… I need to get a few things done daily without the assistance of 3 Velcro dogs… impossible with the new enrichment bowls… I’m not going to return them, my dogs love them once they understand to stay put and lick but my dogs consume things so fast that now it’s just another activity to do with them daily which is fine… but if you have certain breeds it might save your couches and shoes from being chewed but now with the way I have to monitor these things and constantly refill the bowls…( my dogs had them cleaned out in about 3 minutes each) all in all, this was not a smart purchase for me as it’s now added more work to our already busy routines… I can only do 1 star…aftermath photos

Good for a laugh at least and a messy kitchen
Color: black
While design, quality, and ease of cleaning are great!! These are not for highly food motivated dogs and puppies.
My senior dog (100lbs) took a couple licks, he immediately proceeded to pick it up as one unit and carry it to his bed where immediately tore it apart to get to the good stuff. ~ I will say that it is durable and did not fall apart as he carried it.
My 7mo old puppy (60lbs) was intrigued and quickly impatient and was able to flip it over and while this only made a little pumpkiny mess, what he did next was hysterical! He picked it up on the edge and threw up in the air and the mess surprised even him but only for a moment. He promptly did it again and on the third time he was able to break the top loose from the bottom and quickly cleaned up the toy and the mess on my kitchen floor and cupboards.
Fair warning for those with energetically food motivated labs!! These have since been donated to local shelter with the same warning.

Great for dogs
Color: blue
My dog is obsessed with this! I put plain yogurt thinned with homemade broth in it and he’s entertained for a good 15 minutes, as well as being fairly calm afterward.

Good for Chewers
Theme: Football, Size: Large
Dogs love it, they been chewing on it and it's like new. Also I put treats inside and they really like that. I have a small pit mix and a puppy shepherd husky mutt. They play tug of war with it and it's holding up really good.

Great inside toy
Theme: Football, Size: Large
Our Rottie loves these! I wanted something like the Jolly Ball but that is soft for inside the house. She's had a lot of fun with this, picking it up, tossing it, playing soccer, etc.
