Chromatography Bats: Halloween Decorations

About 7 years about EC and I first made chromatography butterflies using coffee filters.  Now BB and I are using the same technique to make chromatography bats for Halloween decorations.

Make sure you follow my Halloween board on Pinterest for more ideas.  Don’t forget to save the pin for later.

To make your own chromatography bats you will need:

  • Coffee filters
  • Wooden pegs
  • Googly eyes
  • Black/orange/purple/red/yellow felt tip pens
  • Cup
  • Scissors

Fold your coffee filter into quarters and cut the wings to make a bat wing outline.

Unfold your coffee filter and colour it in.  I have found over the years that the dark colours, generally, always produce a better affect.

Re fold the filter back into quarters and place it in a cup with an inch or so of water in it.  Over the next 30 minutes of so that water will seep up through the filter paper and separate out all the colours in the ink.

Take the filters out and lay them flat to dry.  Don’t leave them on a surface that will stain as the ink will still be wet.

While they are drying, colour the wooden peg in black and add some googly eyes.

When the coffee filter is finally dry, fold it in half and slide it into the peg.
