Great for Science Experiment

Reviewed in the United States on June 10, 2024

I bought these to demonstrate a science experiment for my kids. They are the perfect diameter and mass creating shock waves in aluminum foil and paper. They leave burn marks on paper when slammed together. Very cool!

Amazing

I bought these for an experiment project and these are the toughest I’ve ever tried to drill. Hardened all the way through. 6 carbide 10mm bits to drill one 25mm deep hole and 5 hours to drill. But the results are perfect. I could not tap them as they are harder than the tap and would not even bite into them. Amazing

Talking about a set of balls, these are a set to be proud of, shinny and heavy.

Bigger than you would think

Reviewed in the United States on June 9, 2024

I bought this 4" for light excersize in confined spaces. No fault of the manufacturer, but it is bigger and more dense than I expected. So again, that is on me. Only reason its not 5 stars is honestly $50 seems a bit high for a ball, but again, thats on me, I paid it. I think Ill be getting a pair of 3" next. More manageable during walks.

I absolutely love this thing and seeing the look on people’s faces when they try to pick it up. Great desktop decor.

Looks Awesome

I bought the 5". "Why on earth would anyone want a 5" steel ball bearing?", you ask? Well, I'm not sure how I've lived so long without one. The shear joy I get when I place it someone elses hand and they have to scramble to get another hand under is beyond entertaining. This thing is solid and HEAVY. The cardboard box was beat to hell upon arrival, but the ball itself, nuzzled in it's bubble wrap armor, was perfectly prestine. Not sure what I'm going to do with it now, maybe order 5 more and make the worlds most badass Newton's cradle, we'll see.
