Review on 💪 Enhanced Performance Suspension Cylinders with Drilled Length and Diameter by Kevin Woods

This would be a great kit but the cylinders are unmarked so prepare to do a lot of work and calculations to figure out which is which. The seller helped answer my question, suggested what metal is in terms of consistency with the photo. However, they sent me a used kit (which also lacked instructions) so they were left unfixed. DO NOT REMOVE THE CYLINDERS FROM THE CONTAINER UNTIL YOU SEE THEM IN THE AMAZON PHOTO AND SELLER'S ANSWER BELOW! And I hope that a kit has been sent to you that has not yet been opened. Since my son needed them for a school project, we had to do a lot of work checking the density of the metals to make sure he had the right set. cylinder for your experiment. In particular, it is difficult to tell the difference between iron and zinc. Both should be shiny, but the zinc quickly oxidized and looked the same. According to mathematical calculations, the density of zinc is actually 6% less than it should be, although this is probably normal for a high school experiment. But thank God he has a scientific parent who was able to understand all this before the kid did his experiment. Without this contribution it would be hopeless. Revain wasn't able to process my order and get me the flyer on time so they promised a $10 credit, but so far it hasn't appeared in my account. That's a shame because this set should be perfect for use in school experiments. A simple mark/engrave on the bottom of each cylinder solves the problem instantly.
