Boats

Ian and Jenny boating on Black Moshannon Lake.

Ian has been learning about boat designs by assisting Mac with full-size boat building.  Ian used his knowledge to create various shaped aluminum foil model boats.  He tested his boats to see how much weight (pennies) they could hold and and how well they moved through the water.

One of Eric's favorite games is Float or Sink.   He puts objects in the bath or wading pool to see what happens.  Eric has discovered that some things, for example washcloths, float at first but then sink when saturated with water.
