Item of the Week

This week’s Item of the Week is the Bubble Speed Tube Set! The set includes three 22-inch long clear plastic tubes containing colored fluids with three different viscosities. Each tube contains a bubble that rises at a constant rate, depending on the fluid and its viscosity. These are a great way to teach students about viscosity!  You can check out the Bubble Speed Tube Set at siuestemcenter.myturn.com.
