You have to have a commitment of people who will get involved in the planning, the preparation for the demonstration, or whatever it is you plan to do and be on hand to staff the event, the event and engage with others. You also want to make sure you've got the right kinds of people. We have a lot of brilliant scientists who may not be the right kinds of people to put in the mall and talk about what they're doing. You have to think about who's giving the presentation. They may be great in creating the idea of what to use and what the learning takeaways are but are they the right people to be out in front.
