If you have to do a science fair project, you might as well make it fun, or at least gross.
Today I came across this blurb:
So I used Google Scholar to find the original article:
E.L. Best, J.A.T. Sandoe, M.H. Wilcox (2011) Potential for aerosolization of Clostridium difficile after flushing toilets: the role of toilet lids in reducing environmental contamination risk; Journal of Hospital Infection, Volume 80, Issue 1, Page 1
During all of that scrambling, I thought about a great science fair project:
How does the type of toilet, affect the distance water droplets fly out?
Look at the question –
What is the independent variable?
(answer: type of toilet)
What is the dependent variable?
(answer: distance of water droplets)
Experiment: Find a bunch of different types of toilets, for example at fast food restaurants, the airport, rest stops, gas stations, etc. Take photos so you can put them on your board.
Figure out a way to measure the distance water droplets get sprayed. Play around with adding food coloring before flushing, try taking pictures with video/digital cameras, try putting down dry paper around the base of the toilet and/or walls of the stall, etc. Flush EACH type of toilet 3 times.
How does the position of the seat affect the distance sprayed?
How does the type of toilet affect the volume of water that leaves the toilet?
