The document describes an experiment using a homemade draught tester to check for drafts in a home. It involves taping a piece of tape to a pencil as a draught tester. The draught tester is held to gaps around windows and doors to see if the tape moves, indicating a draft. For this experiment, the tape only moved a bit, suggesting the home is not very drafty. The document concludes with the observation and results from the draught testing experiment.
