Water seeks its level
There are a lot of misconceptions related to hydrostatic pressure. One of them is that if you took a jug like the one below (or a U-tube, as in my…

Surface tension with a twist
The coolest surface tension demonstration yet! Just because it is AWESOME. Enjoy! Watch the video here. oh, you didn’t think I would only post one video, did you? ;-)
Trying to understand surface tension
Who has an understanding of the effect of washing-up liquid on surface tension on a molecular level? Please help! I’ve recently shown a lot of experiments on the topic of…
Capillary effects
When hydrostatics just doesn’t explain things. Occasionally one notices water levels in straws that are slightly above the water levels in the glass. And of course – even though we…
Surface tension and washing-up liquid
How to destroy surface tension. Remember how in this post my parents sent me a picture of the experiment that I didn’t get to work out? Later the same day…
Surface tension and office supplies.
Lots of stuff an be made to float on water just because of surface tension. This morning, I was taking pictures of heaps of waters on coins. I was planning to…
Surface tension – heaps of water.
The classical way of demonstrating surface tension. When talking about surface tension, the classical thing to do is to talk about the shape of drops of water. As seen before…
Surface tension and water striders
How water striders can walk on water. More pictures from the same spot at the banks of the Pinnau. Looking more closely, you can see the water strider: And now…
