Stop A Strainer Easy Science Experiment
In this fun and easy science experiment for kids, we’re going to see if we can use science to stop a strainer from straining.
- Cooking oil
- Small strainer
- Glass of water
- Pour some cooking oil in the bowl and slosh the strainer around until it is coated in oil.
- Gently shake off the excess cooking oil.
- Now slowly pour the water from the glass into the strainer.
- The strainer should hold the water.
How it Works:
The surface tension of the tiny drops of water are what keeps the water from slipping through the holes in the strainer. The oil also helps by coating the wire mesh, while also making the spaces between the wires a little bit smaller. This creates a very cool effect the you have stopped the water from flowing through the strainer.
Make This A Science Project:
Try strainers with different sized holes. Try dissolving salt or sugar in the water. Try different types of oils. Try different temperatures of water.
