I tested the vented buoy with four sizes to determine which diameter I could use with my test tubes. I used 10.5 mm before, so I tried four sizes by decrementing 0.25 mm each time. The 9.75 mm made it most of the way down the tube, but it stuck part way, and the 9.5 could go all the way. When I stuffed a magnet in the bottom, none of the buoys would fit, and when I checked the model, I saw that the vents were interfering with the magnet socket, so when I combined them, the boy sides bowed out.
