When we did this activity at camp a few years ago, I needed to add food coloring to the bubbles to get colored bubbles. And that worked just fine.
At this writing, Crayola now sells colored bubbles. WHAT A MESS!!
I am embarrassed to say that I bought some for the kids, and for that, I humbly apologize. Son, Jeff, came up with a good idea, but generally I would say that these are more mess than fun.
Use the food coloring….really
What you need:
Fold the posterboard in half.
Draw a half-butterfly on one half. Make sure the body is aligned on the crease (or you will end up with a broken butterfly – and very confused kids)
Cut out the butterfly (if the kids are old enough, have them do the cutting)
Put around 10 drops of food coloring in each of the bottles of bubbles. Use a different color for each. Yellow doesn’t come out particularly well, so I would use Green, Blue, Red and Purple. The Neon food coloring is fun as well…
Make sure the lid is tight and then shake the bubbles to mix the food coloring.
Now you are ready to “decorate”
Blow bubbles from the different colored bottles on to the cardboard.
Let it dry, and voila …. A beautiful butterfly!!
