Fast and fun!
I use this as a STEM station with a staff/volunteer to monitor the table. We use a infrared surface thermometer to act as the laser pointer, and to watch the temperature of the bottle change as pressure changes. Everyone LOVES it, and often they come back to the table to try again and share what they learned to a friend or family member. We have 2 or 3 bottles at the table.
