Her catapult with adjustable legs.

My oldest daughter Megan is involved with the Science Club at school.  One of her first projects was to build a  catapult which would be able to launch a 10g and 25g weight into a specified target.  It needed to be adjustable so that it could launch both weights an equal distance by adjusting the catapult.

Mommy took her to the library and they found a book on catapults.  We picked out a design and Megan started preparing our shopping list.  Megan learned how to use a lot of new tools and construction practices on her catapult.  She's now in the process of fine tuning it for her competition.
