Single-cylinder Electromagnetic 6-12V 2A All-metal Engine Model ToyFeatures:
.Parameters: Piston Diameter: 10mm; Piston Stroke: 7-8mm; 6-12V 2A, support brush ESC, strong magnetic piston support positive and negative rotation, iron piston support one-way rotation.
.Cool Shape: Single-cylinder electromagnetic engine model, mini-shaped, the main body is made of metal, and the overall mechanical sense is full; the production is fine, ingeniously built, the parts are perfectly combined, and the precise production technology is demonstrated.
.Working Principle: The electrical energy is converted into magnetic energy, and then the magnetic energy is converted into mechanical energy to do work. According to the principle of magnetic repulsion and heterosexual attraction, a small amount of electrical energy is used scientifically to generate powerful magnetic energy. Mutual repulsion and mutual attraction within the set range, resulting in extremely strong repulsive force and attraction force, forcing the lower magnet to move, pushing the connecting rod to drive the crankshaft to rotate to complete the engine working process.
.Use Significance and Value: Through the operation model, it is very interesting, and it can deepen the understanding of the structure and operation principle of the electromagnetic engine, and increase the interest in learning scientific knowledge. It is used in science and education experiments or teaching, and can also be used as a DIY model collection.

These are dog tested and approved.
Size: 1-pack
The launcher works very well and will probably last forever unless your dog chews it up while bring it to you to get you to play, but the balls, well, they're not made for labs, that's for sure. That's the bad news. The good news is that worn out or abandon tennis balls fit the launcher just fine. Save your throwing arm. Do your dog(s) a favor. Buy this thing.

No angle for correct throwing
Size: 1-pack, Size: 1-pack
This item does not work. It is about ) inches tall. It’s tiny to bend over and pick up the ball. Has no angel for the ball to throw accurately. Ball goes downward. Would not recommend

Favorite balls
Color: Multicolor, Size: 6 PACK
I never thought that my black lab mix could enjoy a ball more than the slightly larger silicon (sp) ones we have used for years. The sound has her ears up from the moment I pick one up. Please not, these are not indestructible. Throwing them away once they break open (for heavy chewers) is best.
