I love this but it is way too small

Great product at a great price, but I had to do research to figure out which one was zinc and which was steel. No marking or any way to tell if you're not fimailiar already. I do love them though!

I'm not sure what other people would use these for, but they were perfect for my son's science fair project. He put them in salt water and watched them corrode over time. They were the perfect size for this project.

I expected them to be a bit longer. Not labeled, but easy enough to figure out. Good enough for an introduction to density, but I would not use them with glass cylinders.

I ordered them for a science class demonstration. They are very small--smaller than I would have thought. They do a great job for a density activity with a small group of students. But, you can't really hold them up in front of the class.

My daughter used these for a science fair project. She submerged them in water for a few weeks to test if they would rust. It is hard to find small samples of these types of metals so they worked great for the project.

Exactly what I wanted I just wish that they were marked what they were.

These rods are about 2 - 2.5 inches in height. My only remark, is that I wished the metals were marked, as the aluminum and zinc are easy to confuse
