Description

Engino Discovering STEM Mechanics Set- Gears & Worm: Engineering Toys for Kids Ages 9+ (12 Models to Build)Engino Discovering STEM Mechanics: Gears & Worm turns abstract mechanics into action. Young engineers explore gear ratio, force speed trade offs, bevel and crown gears, rack and pinion, and worm drives while building real working machines. The booklet teaches how gears reduce or increase speed, change force, and transfer motion; it also shows how worm drives cut rotational speed dramatically and how screws turn rotation into powerful linear motion.

Engino Discovering STEM Mechanics: Gears & Worm turns abstract mechanics into action. Young engineers explore gear ratio, force-speed trade-offs, bevel and crown gears, rack-and-pinion, and worm drives while building real working machines.

The booklet teaches how gears reduce or increase speed, change force, and transfer motion; it also shows how worm drives cut rotational speed dramatically and how screws turn rotation into powerful linear motion. 

Structured theory, hands-on experiments, and quizzes guide learning, from a carousel speed study to a helicopter gear-train investigation. Build guidance is available in print and online, with a 3D viewer for error-proof assembly. Designed for young engineers to master gears & worm drives through play.

Mid at best
Style: dog ball launcher
It’s mid at best. Requires a little trick to get it to go forward and not just fly up in the air., it’s also not telescoping. It just comes apart into two pieces.

Wouldn’t buy again
Style: dog ball launcher
Compared to the namebrand thrower this one sucks. It just throws the ball way up in the air.

Good size, Durable, Easy to use
My dog doesn't really play with balls that much. But she does love a laser which I was hoping the light in this ball might mimic for her. And it does. She loves this ball. And the winter months when the days are short finding games we can play at the park is critical for her well-being. The ball came in an attractive packaging with a charger and charged quickly. It's a simple push of the button on the light to activate it. It will turn off on its own but light back up when it's moved, which is handy. The light has a soft glow to it which is pleasant to be around. The ball is easy to see at night and has a good bounce to it as well. My dog chewed on it for quite a bit and it's held up really well, so I will say it's pretty durable and chewable. The weight in the ball is nice and it's an easy throw. My only suggestion is to make sure that you have the light piece locked in place first. I have thrown it where the ball and the light went in two different directions. And that was my fault. Lol We have had some great fun with this ball at the park. For the short winter days it's a perfect addition to your pet's play routine. We love it.

Defective on arrival
Second ball defective. First ball received would not light. Second ball battery charged and locked. When unlocked to switch on light, the cylinder stuck in the ball and will not come out. I'm very disappointed. I've sent back and hope the third functions properly.
