This ball shooter is a terrific toy and can be easily made at home. You will need a strong plastic bottle, rubber bands, scissors, thread and a ping-pong ball. Cut a hard plastic bottle about 10-cm from the lid end. You will get a conical cup. Mark four lines at right angles on the rim. Make 1-cm deep cuts on these four lines. You need these cuts for placing rubber bands. After cutting the bottle you can actually see the quarter sections. Stretch a strong rubber band and insert it between two opposite cuts. It will take a semi-circular shape. Place the other band at right angles to it. Both the rubber bands will crisscross in the center. Make a hole in the lid of the bottle. Tie a strong thread on the junctions of the rubber bands and then weave out the wire through the lid and tie a bead at its end. The thread will be the trigger. On the pulling down the thread the rubber bands stretch and form a spring and a ball kept on them will be propelled up. Now place a ping-pong ball on the rubber bands. Pull and release the thread. The ball will be thrown up in the air. Catch it! This work was supported by IUCAA and Tata Trust.
