Low tech floatation-2 litre

But going back to the Spruce Goose, how about modern ultralight ping pong size balls?? Or does that lose to much space between them?

For the professional [img]/images/graemlins/cool.gif[/img] - what about a shape that interlocks and would fit tight??

An old Yankee Boat builder in Connecticut by the name of Earl Brockway was known to use old light bulbs as floatation in the seats of his plywood skiffs.
