THE TENNISBALL CANON
THE TENNISBALL CANON
———————-
PRESENTED BY….
T H E N Y B L E R
THIS IS A
LITTLE GIZZMO THAT MANY PEOPLE
HAVE HEARD OF AND BUILT. IT IS QUITE
SAFE IF BUILT WITH
A LITTLE COMMON SENSE,
AND CAN BE A LOT OF FUN TO MESS WITH.
THE MAIN PURPOSE
OF A TENNISBALL CANNON
IS TO SHOOT A TENNISBALL AS HIGH INTO THE
SKY AS POSSIBLE. I
PERSONNALY HAVE MADE
ONES THAT WILL SHOOT THE BALL SOME 300 TO
500 FEET UP. THESE ARE
A REAL BITCH TO
CATCH.
H O W T O B U I L D
————————-
1) FIRST YOU HAVE TO GET HOLD OF 4 STEEL
CANS. NOT THE ALLUMINUM ONES LIKE PEPSI
USES. THE LAST TIME I CHECKED CHOCOLA WERE
THE ONLY ONES I COULD FIND. A STEEL CAN
ONE. IT WILL LOOK LIKE A SOUP CAN ON
THE
BOTTOM. WHERE AS AN ALLUMINUM CAN
WILL HAVE ROUNDED CORNERS AT THE BOTTOM.
2)
TAKE THREE OF THESE AND CUT BOTH THE
TOPS AND BOTTOMS OUT OF THEM WITH A CAN
OPENER.
THIS MAY BE DIFFICULT BUT IT IS
NECCESSARY
3) THEN GET A CAN OPENER, THE
KIND THAT CUT TRIANGULAR HOLES IN THE TOP
OF JUICE CANS. USE THIS AND PUT AS MANY
HOLES IN THE TOP OF THE FOURTH CAN AS YOU CAN
WITHOUT BREAKING THE TOP OFF.
4)
THEN GET A HOLE PUNCH
OR A SCREW DRIVER AND POKE A SMALL HOLE
(ABOUT 188 INCH
DIAMETER) APPROXIMATELY
122 INCH FROM THE BOTTOM OF THE FOURTH
CAN, AND ON THE SIDE.
5) THEN GET SOME DUCT TAPE, OR OTHER REAL, AND
I MEAN REAL STICKY TAPE.
6) THEN TAKE THE FOURTH CAN AND LINE IT UP
WITH ONE OF THE OTHER THREE, SO THE TOP
LINED UP WITH THE OTHER CAN AS POSSIBLE.
TAKE
AS LONG PIECE OF THE TAPE AND WRAP
ALL THE WAY AROUND THE SEAM FORMED BY
THE TWO CANS.
GO AROUND 2 TO 3 TIMES SO
THE SEAM IS SECURE.
7) NOW LINE THE OTHER CANS UP
WITH THE END
OF THE CAN YOU TAPED, FORMING A FOUR CAN
LONG CANNON, WITH A HOLE GOING
DOWN TO
THE GRATING FORMED BY THE HOLES IN THE TOP
OF THE FOURTH CAN.
YOU CANNON IS NOW BUILT.

———————
1) GET SOME LIGHTER FLIUD FROM THE DRUG STORE.
MAKE SURE YOU GET ONE OF THE
EXPENSIVE
BRANDS, THEY TEND TO GIVE A HIGHER EXPLOSION.
2) GET A TENNIS BALL.
ONE THAT YOU DON’T MIND
GETTING A LITTLE SCORCHED. AND MAKE
SURE IT FITS IN THE HOLE
IN THE TOP OF THE CANNON.
3) NOW PUSH THE BALL IN THE TOP, YOU WANT IT
TO SLIDE
AS EASILY AS POSSIBLE TO THE JOINT
BETWEEN THE SECOND AND THIRD CAN. USE A FILE
TO
SMOOTH THE JOINT BETWEEN THE FIRST AND SECOND
CAN, AND ON THE JOINT BETWEEN THE SECOND AND
THIRD PRESS
A LITTLE ON IT TO PREVENT THE BALL FROM
SLIDING FURTHER.
4)
REMOVE THE BALL AND GET SOME MATCHES READY.
MAKE SURE YOUR OUTSIDE.
5) SQUIRT
SOME LIGHTER FLUID DOWN THE TOP,
NOT TOO MUCH OR IT WON’T VAPORIZE, AND
IT IS THE
VAPORS THAT EXPLODE.
6) WAVE THE CANNON AROUND, AND BLOW IN THE
LITTLE HOLE IN
THE FORTH CAN TO HELP SPPED UP
THE VAPORIZATION.
7) THEN SLIDE THE BALL IN THE
END MAKING SURE
IT STOPS AT THAT 2-3 CAN JOINT, AND SET THE
CANNON ON THE GROUND.
THEN, MAKING SURE YOUR HEAD ISN’T OVER THE
END, LIGHT A MATCH AND HOLD IT UP TO
THE
LITTLE HOLE IN THE BOTTOM OF THE FOURTH CAN,
AND B O O M!!!
9) IT’LL
SCARE YOU AND IF YOU ARN’T CAREFUL
MAYBE IT’LL GET YOUR FINGERS A LITTE,
BUT IT SHOULD
GO.
HINTS TO THOSE WHO HAVE TROULE WORKING.
—————————————
– TRY DIFFERENT AMOUNTS OF LIGHTER FLUID
TIME. THEY SAY A 1 PART FUMES TO 12 PARTS
OXYGEN IS BEST.
– MAKE SURE THE BALL CAN GET OUT AND DOESN’T GET
JAMMED IN THE
END.
– AFTER EVERY 3 OR 4 SHOTS DROP A MATCH
DOWN THE END TO BURN UP EXCESS
FLUID IN
THE CANNON
