Got this to use for a classroom demo. It’s ok but not great. The smallest tube had air bubbles that I couldn’t get out and really messed with the visual comparison with the other tubes. I ultimately thought it would be confusing to the students. They did, however, refund me without making me return it, so that was nice.

This is a good science kit but there are a few errors. The glass stem to hold the set should not be hollow. It gives wrong measurement for the narrowest capillary tube. Either it should be solid or it shouldn't but right under the narrowest tube. The other error is the bend at the end of the tubes is not a right angle. That gives an error when measuring the height as well.Anyway, this is great to teach the basic concept. If they can fix the two errors, this would be a great product.
