Giant bubbles

Summer fun with bubbles, the secret is glycerine

You will need a straw, some string, water, washing up liquid and glycerine

Cut the straw in half

Cut a piece of string as big as your outstretched arms

Thread the string through the straws and knot so you have a circle of string

The two straw pieces are your handles

Mix the water, glycerine and washing up liquid together

For 400ml of bubble solution you need, 380ml of water (95%), 12ml of washing up liquid (35) and 8ml of glycerine (2%)

Mix them together being carefully not to make the mixture foamy

Put your circle of string in the mix, collecting a film of the mixture

Carefully pull the straws apart and lift up to fill the film with air

Loosen the circle and close to release the bubble
