Low-cost interactive activities and partnerships for a neighborhood street fair.

[Noah17]

I'm helping organize our neighborhood's annual summer street fair, and we're trying to make it more engaging for families this year. We have the basic food trucks and live music covered, but we need ideas for interactive, low-cost activities that would appeal to kids and adults alike. For those who have planned similar community events, what were your most successful activity stations or partnerships with local businesses or clubs that added a unique touch without blowing the budget?
