An
Exercise in Rocketry at Vanderbilt
Dyer Observatory
Tennis Ball Nose Cone
This should only be done by an adult! Do not
hold the ball in your hand while cutting. You might pierce the other side
and your hand.
Lay the ball down to make incisions. Cut slots just slightly larger than the
diameter of the cap.
When you force the ball onto the water bottle/nose
cone/payload bay, leave the cap on.
Leaving the cap on will strengthen the bottle and make it easier not to crush
the bottle
when applying. If you make the cuts in the ball too big, you will find it
more difficult to apply.
