There comes a time in every mad scientist's life when their invention will require capacitors. They have to look cool, show off how inventive you are and pay homage to earlier inventors. Shop bought capacitors just won't cut the mustard. No, you need Leyden jars.

Step 1: Materials Needed

List of materials:

  • A plastic hand wipe jar
  • Aluminium foil
  • Glue
  • PVC pipe
  • A plug chain
  • Metal washers
  • A piece of wire
  • A plastic shopping bag

Step 2: Base Plate

Firstly make sure your container is clean and free of labels. Cut one circular piece of Aluminium, slightly wider than the diameter of your container. I used a bowl because it was big enough for my needs. Cut slits around the edge of the circular Aluminium piece, these are so you can overlap them. When you've done cutting your foil it should look like a flower head with petals. Curl the petals of the Aluminium until it looks a bit like a bowl. Now glue the base section in place, making sure you go partway up the wall.

Step 3: Inner and Outer Walls

Now measure and cut two rectangular sheets of Aluminium, big enough to wrap inside and outside of your container, these should slightly overlap. Then you can put the Aluminium on the inner and outer walls and glue them into place. Ensure your inner wall connection overlaps the base section. Also make sure your Aluminium foil is nice and flat against the surfaces, remove any air pockets where necessary.

Step 4: Making the Top Contact

Next we need to suspend a metal contact through the lid, so it touches the inner Aluminium. For this I'm using the chain from a sink plug, suspended from the existing hole. Put your metal washers on so they sandwich the lid of the container and lastly tighten your nut - this only needs to be hand tight.

Oh, I'm disappointed - I thought you were going to use the actual wipes!

(Sorry, good job, really!)
