The main thing that you'll need is a nice country lake that you can
collect some mud from. You'll also need:
Cut off the top of the soft drink bottle, and save the top to use as a funnel. Also, if the bottle has a label on it, remove the label (soaking it in warm, soapy water will help).
This project is a bit messy, so you may want to do most of the work outside. If you have to work indoors, spread some newspapers around to protect the floor and table, and keep a window open because it will get smelly!
