Poinsettia pH paper

To make the Poinsettia pH paper:

1. Cut the flower petals (actually specialized leaves called bracts) into strips
   
2. Place the strips into a beaker.
   
3. Add enough water to cover the plant material and simmer on a hot plate. 
   
4. Filter the liquid into another container (such as a shallow petri dish) and discard the plant matter. 
   
5. Saturate a piece of filter paper with the poinsettia extract. 
   
6. Allow the filter paper to dry and cut the colored paper into test strips.
