Newton's Law with raw eggs. Egg will fall into the cup unbroken when pie plate and 'tower" go flying. Pinner said she wished she had a camera or her husband's face when I knocked the pie pan! The kids think this is SO cool!
This website has a "Recycle Your Wedding" section where brides can sell decorations from their wedding. Worth a look before you buy 80 square vases. i'll be happy i pinned this one day. Good site for party ideas and supplies
