Wriggle Worm Experiment
 
The Wriggley Worm
Materials you will need:

• Glass of water
• Drinking straw with tissue wrapper

This is a moving experiment!

 

 
 
Steps
 

1.  Carefully tear or pintch off the top bit of tissue paper from one end of the straw.

2.  Whilst holding on end of the straw and paper, slowly push the tissue wrapper down the straw so that is forms crinkles (wrinkles). Try to keep the crinkles nice and tight.

3.  Carefully remove the crinkled paper wrapper from the straw and lay it on the table (see photo below).

Note: It may take you a couple of times to master this so have a few spare straws on hand.



4.  Dip your straw in the glass of water and place your thumb on the top hole of the straw to trap a bit of the water in the straw.

5.  Remove the straw from the glass and release a drop of water from the straw onto the straw wrapper by moving your thumb away and watch what happens.

Here is an example of what happens:
