Introduction: Water Bottle Capacitor
This capacitor probably won't be the strongest, just saying.
So, here's what you need:
1x empty water bottle
Vinegar
Copper Wire
Tin foil
Step 1:
Start by filling the water bottle 70-80% full with the vinegar.
Step 2:
Next, poke a hole in the top. You may use a nail and a hammer.
Step 3:
Put the wire through the hole, so it goes well into the vinegar.
Step 4:
Bend the top of the wire, so it doesn't fall through.
Step 5:
Wrap a good amount of tin foil around the outside of the bottle, and tape it in place.
Step 6:
Connect one alligator clip the some of the exposed tin foil.
Step 7:
Connect the other one to the exposed wire
Step 8:
Connect the ends of the clips to so one goes to each of the leads of a 9v power supply. Take note of which clip goes to positive!
Step 9:
Leave it on for an hour.
Step 10:
Now it's ready! It should look like the pictures above. Good work :)
