I love making waterbottle rockets but can't be bothered putting in the work to make one with fins and remote releases and all that rubbish,so I have made a rocket that is just as fun but is so simple that my friends 5 year old brother made one.

Step 1: Stuff You Need

to keep it simple I only use 3 things :
compresser
drill
bottle

5 if you count water and air

Step 2: Drill the Hole in the Cap

with the drill

Step 3: Just Add Water

fill the bottle about half full.

Step 4: Launch

slide the compresor into the bottle when it is on.
pause for about 10 seconds.slide the bottle off the compressor and get out the way.
if there is a leak get a new cap and start again.
you will get a little wet
warning:dont point at people.
