Ping Pong Dunk


Our goal: make a contraption that moves
a ping-pong ball out of water to a different
container
Parts were made from Wal*Mart specials
and sticks from Melrose Courtyard
Our Design




Allow glass ball to roll down ramp
into a container placed on a lever
Lever pulls down which causes
fishing wire to pull water bottle up
Water pours into funnel and cup
Platform and ping-pong ball float to
top and ball falls into next container
~Energy Conversions~





Potential energy converted to kinetic
by ramps
Transferred by>>>lever!!!
Creates tension in string which
releases potential energy of H20
Force of water pushes platform up to
release potential energy of ball
Ball then falls into a container
Conclusion


Issues: finding a ball with the
correct mass needed to pull water
bottle, creating the fulcrum, making
the ping-pong ball fall in a
designated direction
Learned that designing things and
creating the design are much harder
than it seems
