Step 1: THINGS YOU NEED

Picture of THINGS YOU NEED
YOU NEED:
*PVC PIPE
*ARALDITE RESIN
*CORNER PIECE OF PVC
*DUCT TAPE
*SHUT OFF VALVE
*THIN PIPE
*BOTTLE WITH TOP
*VALVE FROM A BIKE TIRE
*SLECTION OF DRILL BITS
*BIKE PUMP

Step 2: MAKING IT

Picture of MAKING IT
FIRST WRAP THE HOLE BOTTLE WITH DUCT TAPE TO REINFORCE IT

THEN DRILL A HOLE IN THE SIDE OF THE BOTTLE SO YOU CAN FIT A TIRE VALVE IN IT

PUT THE TIRE VALVE INTO THE HOLE WITH THE THREAD FACING OUTWARDS

SEAL THE HOLE WITH A LOT OF RESIN

THAT IS THE BOTTLE DONE

Step 3: THE PIPE

Picture of THE PIPE
GET A CORNER PIECE OF PVC AND ATTACH A PIEC OF PVC ABOUT HALF A FOOT LONG AND GLUE IT TOGETHER WITH RESIN

AT THE END OF THE PVC PIPE ATTACH A SHUT OFF VALVE TO THE PVC AND SEAL IT WITH RESIN

AT THE OTHER SIDE OF THE SHUT OFF VALVE ATTACH ANOTHER PIECE OF PVC TIT AND GLUE

THEN PUT THE THIN TUBE TO THE END OF THE PVC AND GLUE

GLUE THE CORNER PIECE TO THE END OF THE BOOTLE TOP BY DRILLING A HOLE IN THE TOP OF THE BOTTLE AND GLUE THE TOP TO THE BOTTLE

Step 4: HOW TO FIRE

TO FIRE YOU HAVE TO CHECK THE SHUT OFF VALVE IS CLOSED AND PUT A BIKE PUMP TO THE BIKE VALVE AND INFLATE TO 50 PSI BUT NOT MUCH MORE SINCE THE PRESSURE COULD BUILD UP TOO MUCH AND EXPLODE

WHEN YOU HAVE PUMPED IT UP TO THE CORRECT PRESSURE PUT WHATEVER AMMO WILL FIT IN THE THIN TUBE SUCH AS:
*BB'S
*WET TISSUE
*PELLETS
AND ANYTHING ELSE YOU CAN THINK OF

THEN LOAD IN YOUR AMMO AND OPEN THE VALVE FULLY AND IT WILL FIRE

i use a small butane gas thing for my stove now
Oh cool . I modified a airgun with 3 2ltr cola bottles holding about 125 psi each with a compressor in a backpack to hold bb bullets its not exactly safe holding 375 psi on your back But its alot more powerful than a normal bb gun

wrap duct tape round it so if it explodes it wont be as bad
Ive strengthened it using my methods i was Saying earlier (ible coming lol) and then wrapped Duct tape around then its got a load of memory foam i had left over it stops the bottles Jinglinh and isnt as much stress on my back So it should be ok !
I would not use capitals the whole instructable.
