Make Your Own Bottle of Gillyweed

Gillyweed was important to Harry Potter in the fourth story, Harry Potter and the Goblet of Fire. It was Gillyweed that allowed Harry to breath underwater, thanks to the gills Harry grew after eating the magical plant.

This video shows you how to make your own Gillyweed. You can show off your bottle by wearing it as a necklace or simply placing it safely on a shelf.

Before I watched the video I was concerned that the cork might come out, spilling the contents of the bottle. I was surprised to see that this is not a concern because the inside is filled with glue, not water. Clever!

What You Need To Make This Bottle Of Gillyweed

  • Small glass bottle with cork
  • Gravel (small enough to fit in bottle) OR
  • Sand
  • Food coloring
  • Plastic cup
  • Toothpick
  • Lichen
  • Elmer's clear glue
  • 20 gauge wire
  • Round nose pliers/wire cutter
  • Silver chain
  • Bent tweezers (optional)
Do You Need Any Of The Above Items?


Add a small amount of rocks (or sand) to the bottle.

Fill bottle half full with glue.

Use a plastic cup to mix a few drops of the green and yellow food coloring to a small amount of glue. Stir with a toothpick until mixed.

Add some of the colored glue using the toothpick to the bottle and mix it a bit with the glue above the rocks.

Add lichen to the bottle. You might find it helpful to use bent tweezers, like the woman in the video does. The tweezers will make it easier to put the lichen into the bottle and glue.

Add more glue to the bottle, then add and mix more of the colored glue to the glue you just added.

Put a bit of glue around the sides of the cork, then firmly insert the cork into the bottle.

Wrap the 20 gauge wire twice around the neck of the bottle. Cut the wire about an inch above the neck (see video if this doesn't make sense), then use the pliers to make a loop with the remaining wire. Make sure there are no holes or gaps in the loop so you can insert a necklace chain if you want without the chain falling off.
