DjuiinoStar Premium Gyroscope: Sturdy&Durable, Pass 2nd Floor Drop Test, Long Spin Time (Play Tricks at Ease, Use Ball Bearings), Educational Physics Anti-Gravity Toy DG-5B

Great demonstration for my Physics project in class. This is heavier than the other gyroscopes, but more stable. You should avoid putting them on top of tables since they'll fall of far to the ground. The instructions were clear and not too much assembly needed.

This is an excellent fidget toy for my Integrated Physics and Chemistry (IPC) class that helps create an interest in the content I teach. This thing is extremely durable, which is what I need since I’m working with rambunctious 14 year olds. The string you crank it with is also of excellent quality. I’ve read some reviews about it being too heavy and was mentally prepared for that, but have had no issues at all with its weight. I am however a fairly strong, 220lb man who grew up as a kid cranking lawnmowers like it was his job…well, I suppose it was.

Not balanced at all!

Spins for a LONG time!

My boyfriend is obsessed with this. Great quality.

I bought this for my grandson because his sister broke the first one I sent him. I waited to write the review because I was not sure how he would like it, and I have not opened it. He loves it and says it is sturdier than his first one and well balanced. That’s all I need to know so I would recommend it.

I teach existing pilots to fly a specific type of jet aircraft and had one of these kids come though that was all about pushing buttons but had extremely few hours hand flying an aircraft. I went back to the basics to determine his knowledge level and found him lacking in a lot of aerodynamics basics including this subject so I bought the gyro for him which kept him entertained for a short while. This is a NICE piece of work and ball-bearings make a huge difference in run time. Quality training instrument, much more than a kids toy I thought.

Says what it does and does what it says! This gyroscope is of surprisingly high-quality and comes with excellent bearings that enable the flywheel to spin fast enough to show how gyroscopic precession works. Great for teaching young kids about gyroscopes. Highly recommended and would buy again.

Espetáculo. Ótimo recurso instrucional para lecionar momento angular! Logística perfeita e veio com nota fiscal (alguns vendedores da Amazon não tem enviado nem digitalmente e nem em papel).
