Introduction: Electricity Powered Bottle Rocket
bottle rocket is a bottle shot up by water escaping with pressure
in this rocket the pressure is created by vaporizing the water inside the bottle with electricity

Step 1: Attention
this project brings together water and electricity. high pressure of steam and oxygen / nitrogen mix are created here
it is VERY easy to electrocute / start a fire / hit by hot steam and sharpnel / get injured or killed in other ways
if you dont know how to remain alive - this project is not for you !
if you know - its up to you and entirely on your responsibility
check that everything is unplugged before you touch. i know its obvious but i just tend to get shocked myself all the time

Step 2: Materials
2 plastic bottles
electrical cable with 2.5 mm2 copper wires (aluminium not recommended)
hard copper wire
aluminium foil
wine cork
hot glue or silicone window sealant
water
food salt (NaCl) (optional)
available 110 / 240 V electricity source capable of 10 A (240 V) or 20 A (110 V) for short time. 30+ / 40+ A recomended (most 16 A circuits can give 30 - 40 A for few minutes without tripping breakers)

Step 3: Isolator
cut a shet of plastic from the cylindrical part of a large bottle
roll it to a pipe. width is about 1/2 the neck of the bottle. height is 2/3 the height of the bottle
catch it with sticky tape
cut 2 holes near its center about 1 inch apart

Step 4: Cable
strip the end of the cable. leave long wires as seen in the image. the ground wire is not needed
drill the cork to get the cable through
insert the cable into the cork. seal with hot glue or window sealant from the side thats in the bottle
push the cable into the isolator and get out the wires through the holes
the wire close to the cork should be neutral. otherwise the wet cork may attract leak currents and kick out your rcd

Step 5: Electrodes
wrap the isolator with aluminium foil from the exit of each wire and to its end
wrap tightly hard copper wire over each electrode. leave free end near the exit of the wires
connect together tight the supply wire and the copper wire of each electrode
bend everything down so its free to go through the bottle neck

Step 6: Plug
wire the plug to the cable
dont connect the earth wire. its other end may attract leak currents and kick out your rcd

Step 7: Got Ready ?
fill the bottle with enough water to cover the entire isolator
close the bottle. push the cork in with a force that still allows you to pull it out with your hand without difficulty
when you try this for the 1st time use just water. if you want higher current (faster reaction) next time mix some food salt (NaCl) in the water
set up the bottle in vertical position. its ready to fire !

Step 8: Water Rocket Go !
plug it in and wait few minutes
be ready for shut down rcd when it flies (electricity and water are now outside the sealed bottle)

Step 9: Anarchy
if you ues the bottle cap instead of cork the bottle will blow up
the amount of air in the botte determines how much time it will take to blast. to get the blast faster fill the entire bottle
even with full bottle it takes long time - unless you put in a lot of salt and give it huge current
be ready for a short circuit and kicked off breakers once it blasts. to avoid it add a high power resistor (like electrical heater without motor) to the circuit. the resistor lowers the current so youll have to wait longer
