You can do this very exciting experiment on Surface Tension with ordinary things. Fill the glass with color water. Cover it with a plate and then invert the plate. Now gently tilt the glass on its edge and quickly wedge a coin between the glass and the plate. Mop up the water and wedge more coins. Despite the gap between the glass rim and the plate water does not flow out because of surface tension. http://www.arvindguptatoys.com/toys/airpressuref.html This work was supported by IUCAA and Tata Trust.
