Day 32:

"Make something ephemeral.  Can you create something using a materiel that will dissipate quickly, like soap bubbles, smoke, butter on a griddle, or cream in coffee?"

This was hard.  First trying to make soap bubbles with products that don't produce a lot of bubbles was a challenge.  Then making my tree from the bubbles proved difficult as the moving of the water to shape the tree would continue to tear it apart as well.   Trying to dry my hands quickly to handle the camera for a picture.  And finally the picture itself of white bubbles in a cream bathtub.  In hindsight I should have added some food colour to the water to give a better background for the tree.  Anyway these are the results:

If you use your imagination you can see the tree.  Cheers
