Vanilla extract, small balloons, eye dropper, Plexiglas box

 

Code Number: 4D50.65

Demo Title: Diffusion Through a Balloon

Condition: Good

Principle: Pressure Diffusion

Area of Study: Thermodynamics

Equipment: 

Vanilla extract, small balloons, eye dropper, Plexiglas box.

Procedure:

Place 10 to 15 vanilla extract into one of the balloons being careful not to get any on the outside.  Blow the balloon up to a reasonable size and place in the box.  After a few minutes open the box and a very noticeable smell of vanilla will be present.
