TF9.4 Water Wedges
A thin vertical wedge with a hollow middle is partially filled with dyed water. The class sees that the water is lower at the thicker end and higher at the thin end. This is due to the adhering nature of water. Doing the same with mercury will give the opposite result. This is similar to the positive meniscus of water and negative one of mercury. When using mercury, there is a special block and wax cover to use with the wedge in F25. Please use extreme caution when working with Mercury.
