•100g KY jelly
•1 level tspn sodium bicarbonate (baking soda)
•1½ cups detergent concentrate
•1 cup hot water
•Filtered water to make up 2 litres
•1 x 2 litre plastic bottle
•1 small bucket
•2 x 1 metre lengths of wooden dowel
•5m natural fibre string
Dissolve the sodium bicarbonate in the hot water. Carefully mix in ½ cup of the detergent, all the glycerine and the KY jelly. Stir until dissolved as much as possible. Pour about 1 litre of cold water into the 2 litre bottle. Slowly pour in the remaining 1 cup of detergent, taking care not to make foam. Very slowly add the warm glycerine/KY/detergent/water mix. Add water to bring to 2 litres.
Gently rotate the bottle until the contents are mixed as much as possible (there will probably still be undissolved NaHCO3 and visible threads of KY & glycerine – don’t worry). Leave the bottle to stand for 2 days.
Meanwhile braid the string into a loop about the size of a basketball and attach to the ends of the dowel like this:
After two days have passed, check the solution and make sure it is completely uniform – there should now be no visible traces of any of the individual ingredients.
Now, go to a park or a beach – somewhere sheltered and not too hot. Pour some of the solution into the small bucket and dip the string into it – make sure you get it nice and saturated. Now do this:
You might even be able to make one like this…
Science! Just because something isn’t imaginary doesn’t mean you can’t believe in it…
