Metal V2 Electromagnetic Reciprocating Piston Engine Model Motor PhysicsFeatures:
.V2 electromagnetic engine model, mini modeling, designed with CAM, the main body is made of metal material, the overall mechanical sense is full; Fine production, craftsmanship, perfect combination of parts, highlighting the precision of the production technology.
.6-12V voltage supply, 2S-3S lithium battery is recommended. The strong magnetic piston supports positive and negative rotation, and the iron piston supports unidirectional rotation.
.Electromagnetic Engine Working Principle: Electrical energy into magnetic energy, the magnetic energy into mechanical energy to do work, according to the same, opposites attract magnetic principle, scientific use a small amount of electrical energy to generate strong magnetic energy, by each cylinder magnet in mutual exclusion, and set the scope, produced strong repulsive force and suction force, force the magnet, The connecting rod drives the crankshaft to rotate to complete the working process of the engine.
.Wide Application: Through the operation of the model, full of interesting, but also can deepen the understanding of the electromagnetic engine structure and operating principle, improve the interest in learning scientific knowledge, for scientific teaching experiments or teaching, can also be used as a DIY model collection.
.Note: 1) when using the machine model, please do not run for a long time, the power of enameled wire is easy to generate heat, strong magnetic field at high temperature for a long time is easy to weaken the magnetic, machine operation has a certain impact, the temperature is too high, please immediately stop running, to prevent scald (the limit temperature of strong magnet 80℃, enameled wire 200℃). 2) The piston mouth of this machine is an open cylinder hole, inside is a strong magnetic piston, easy to attract iron metal objects to the body, resulting in the piston stuck, unable to run. Also do not add lubricating oil in its internal, resulting in adhesion of more dust. 3) This product is suitable for people over 14 years old to use, play, static display, etc.

Needs to sell replacement popcorns
Style: Popcorn Bucket
My dog love this toy however, we have 5 popcorn buckets and only two popcorn balls left. It would be great if there was way to just buy the replacement popcorns. I haven't found them anywhere though.

Bento Ball for the Win!
Size: Large
I got the Starmark Everlasting Bento Ball for my doodle, and it’s quickly become one of their favorite toys.
First off, it’s super durable—which is a must for doodles that love to chew. This ball is made from tough material designed for aggressive chewers, and it actually holds up really well over time.
What I love most is the mental stimulation. You can fill it with treats or kibble and even add a harder “cap” treat on top, so your dog has to work for it. It keeps my doodle busy and entertained way longer than a regular toy.
The erratic rolling design is another win—it doesn’t just roll straight, so it keeps your dog engaged and curious. Bonus: the textured surface helps with light dental cleaning while they chew. 🦷
👍 Pros:
• Extremely durable (great for doodles/chewers)
• Keeps dogs mentally engaged
• Doubles as a slow feeder
• Easy to clean (top-rack dishwasher safe)

Very Durable and keeps dog busy
Size: Medium
We have a dog who loves to chew up EVERYTHING!! She is constantly getting into things and if she can't reach an item of interest, she will find a way to get it, even if it means jumping up on the counter or pool table. LOL. We've tried every puzzle toy and treat you can imagine to keep her busy and tire her out mentally, but nothing really worked that well. She would figure the puzzles out quickly and become board with them after several uses, and preferred to try and chew up the plastic instead. Treats, like bully sticks, that should last a "long time" were gone within 10 minutes. I didn't have high hopes for this product given the history of our dog, but I WAS WRONG!!! The treat was already in the ball when it arrived, so I gave it to her like that. She licked, pawed, and chewed at this treat for hours and did not get board with it. She wore down a little of the dome shape on the treat by the end of the night, but there was still a lot left when I took it up. I gave it to her again the next evening and again it kept her busy. By the third day, the treat was worn down to a ring shape so I took the treat out of the ball and gave it to her. She ate it in about 3 minutes. After examining the ball, it is still in good shape with no damage like we found with hard plastic toys like the kong wobbler. We will definitely be ordering the refills to use with this ball. Best product we have found for busy, destructive dogs who become board easily.
