I'll get you my pretty.

It was the perfect assignment.  The perfect mix of butterflies, rainbows and engineering stuff.  The perfect scenario for some father, daughter bonding.  Perfect for me since it was not my area of specialty and I knew she would take full ownership of making sure it embodied everything she could imagine within the limits of my craft box.  And what was this assignment?  

Make a fairy trap using at least 2 simple machines.

The fairy sees the magic wand and as she lifts it to take it, the cup with the butterfly on it falls and traps her.  Yes, she got the perfect grade too!
