If you are a business with a hands-on skill component - florist, electrician, builder etc.
Bring some elements of your business for the members to try what you do. For example, the members try to create a small floral arangement, or wire some fiddly wiring.
The idea is to give them a tough task, so that when they see the professionals do it, they realise the skill involved in doing these jobs - plus they will have lots of laughs and a 10 minutes they will remember.
