I had three cupcakes on the box at a time, with the pamphlets in front. I positioned myself in front of a shopping centre, where a good amount of people would be walking past, holding the box and saying "Free Cupcake!" whenever someone walked past. It was a great experience. I had a lot of interest, and gave out all my cupcakes within two hours.
This is something anyone could do. You don't need to be a part of any organisation, it's cheap, doesn't require much setting up, and it's a great and fun way to educate people about veganism. When you don't have much, but you want to get vegan education into your community, get creative and work with what you have!
Hand out vegan food, host cooking classes, make videos, write, do a market stall, hand out pamphlets, do whatever you feel comfortable doing - There are many ways you can promote veganism!
