Step 1: CUT a BOTTLE AND a SOCK
Cut the bottom of the bottle off, then cut your sock so you are left with toe half.
Step 2: ASSAMBLE
Put your sock onto a bottle as shown and secure it with some rust tape or rubber band.
Step 3: MAKE a SOAPY WATER
Pour washing up liquid like fairy or any other into a tray. One or two table spoons. Then pour half a cup of water into it and mix it well.
Step 4: MAKE a SNAKE
At the end it should look something like this. So soak a sock into soapy liquid, and blow into a bottle. an amazing snake will start to form. it's a lot of fun and is especially great use outdoors when it's sunny. :)
OPTIONAL: You can add some food colouring onto a sock and then you'll get rainbow snakes :)
