Press-fit tubing-attachment flange for CO2 bubbles experiment.

SummaryI made a tubing-attachment flange that I press-fit onto a plastic jar so that I can create a source of CO2-mist to blow bubbles. The boys and I had a lot of fun with these CO2-mist filled bubbles!InstructionsPrint. Cut hole in jar. Press-fit pieces to clamp the jar in between. Attach tubing to the flange. Place water + dry-ice in jar and seal the lid. Use CO2-mist stream to blow bubbles at the other end of the tubing.
