1. Tear or pintch off the top bit of tissue
paper from the straw.
2. Whilst holding on end of the straw and paper, slowly
push the tissue paper 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.
4. Dip your straw in the glass of water, placing your thumb
at the top of the straw to trap a bit of the water.
5. Release a drop of water from the straw onto the straw wrapper
and watch what happens.
