The tristring is invented by the toy inventer Kalvin Klundt and has been sold in toy stores, but you can easily make your own.

You will need:

  • Two sticks, e.g. 20 inch flower sticks
  • Thick cotton strings with a length of ca. 6 feet (the string should not be too thin)
  • Two rubber bands
  • Soap bubble liquid

Here is how to build it.

Tie the ends of the string to form a ring. Place the rubber band on the stick end and place a small loop of the string on the top of the rubber band on the stick.

Think about

  • If you let children use the tristring, please make sure that they do not get the sticks in their eyes.
  • For good results your soap bubble liquid is important. You can for example use our recipe.
