Magic Mud

Do you know the joy that is Magic Mud? A sacrifice of a box of corn starch, some water and a few drops of food colouring have equalled a week-end of fun. We make it maybe once every six months, and  it is always a hit.

Push on it and it resists, stay still and it allows you to sink. Liquid to solid, solid to liquid, it is hours of mind expanding fun — all at a kitchen table.

  1. How cool! My grandson will love it. Me too, truth be known. I once did an accidental science experiment in my microwave. I needed buttermilk for a recipe and didn’t have the real thing so I did the vinegar in milk thing. The milk was really cold so I thought I’d speed up the process by warming it with the vinegar in the microwave. I guess I nuked it too long and the result was this very strange slime mixture that I could stretch into long strings. I haven’t tried it again but it was sure fun at the time!

  2. oh my goodness! we are *so* doing this – and soon!!
    thanks for the inspiration!

  3. Hooray for thixotropic mixtures! Yeah, I know I’m a geek!

  4. Thanks for the tip, Kate – I’ve never heard of it before but Solids Liquids and Gases was last year and we barely did any hands-on stuff…we’ll do this one for sure.
