Soapy Science Bubble Walls and Bubble Frames Soap film always attaches by forming the minimum bubble surface from edges of one frame to the other. Explores principle of surface tension, color, and flexibility.
Students form soap bubbles and surfaces several feet high through a pulley system.
Desktop version is made with drinking straw and coffee stirrer frames for students to experiment with the platonic solids. A converted plastic slide where students experiment with shapes to observe resulting wave patterns. Water and soap mixture is recycled through a submersible pump. Using a water table with electrical pump, and Kalliroscope Fluid, students are able to simulate ocean currents, coastal erosion, aerodynamics, and convection. The downscaled acitivity can be done with soap, water and plasticene in dishpans, effectively demonstrating how the Gulf Stream is created and why it flows like it does.
