Tech Fest Work

Dave came up with a wonderful CO2 based game to engage students for Tech Fest.  We want to set up a game where the students blow into a straw which is connected to individual containers that each has a CO2 sensor set up in it.  The 1st student that gets the highest concentration of CO2 (3 to 4 competing at a time) gets to blow bubbles at a container containing CO2.  Since CO2 is more dense than air and is invisible the students will see that CO2 is present in the container due to the bubbles coming to rest on the top of the CO2 layer.  Rough sketches are below for the room layout.

Dave is going to write a formal proposal for approval by Dr. Thompson.
