Egg launcher

Gary had a bring your child to work day a couple weeks ago and Bryant was old enough to take part.  One of the prearranged activities they do on this special day each year is have an egg launching contest.  Whichever egg is unbroken, launches the furthest, and looks/sounds coolest will win (apparently some of these engineering fathers add sound effects and lights to the launcher).  There is a long list of requirements that must be followed or your egg will be disqualified (you cannot hard boil your egg).  Here is a picture of Bryant with the launcher he and Gary made.  They did not win the contest, but their egg did not break when launched.
