BTL Activity For A Toothpaste

I require unique ideas for a BTL (below the line) activity for a toothpaste in a mall. Its targeted to 28 to 40 years old. Any ideas will be appreciated.

Jay’s Answer: How about a toothpaste art contest (drawing with the toothpaste itself) in the mall, with everyone welcome to join in. Separate categories for adults, kids, families, etc.
