Rules of lab safety


  1. Safety glasses - protect your eyes
  2. Wear a lab coat - protect your clothes
  3. Lab behaviour - appropriate behaviour to keep safe
  4. Use proper equipment (ask if you have never used before)
  5. Always clean up your mess



Experiment: Making a cloud

Equipment:

-rubbing alcohol
-bottle (plastic) with lid
-matches



Method: Pour a small amount of rubbing alcohol into the bottle.
Light a match and blow it out so smokme is produced. Hold your bottle under the match while squeezing. Blow out your match so it produces smoke, and release the bottle so the smoke is sucked into the bottle. Immediately close the bottle tight with the lid. Squeeze bottle as hard as possible and release - the bottle should fill with a cloud.
