The Floating Paper Clip Experiment
Alter the surface tension of water, so that you can make a metal paperclip float. This easily performed science experiment has astounding results that will have children of all ages actively engaged in exploring the science of surface tension. This wonderful experiment defies your predictions and is definitely worth taking a few minutes to explore.
After you perform the second part of this this experiment when the paperclip floats, take a close look at the surface of the water around the paperclip. You can see how the surface tension has altered. It looks a bit like a skin has formed on top of the water but actually the water has been pushed down beneath the paper clip and has raised slightly inside and around the paper clip keeping it afloat.
