Ice cream music businesses

There are a lot of products you could sell with a ice cream music horn setup. You could sell other things with a music horn like comics,soda,vitamin water,water, chips.nachos all this can be prepackaged and sold, doing this in a car to start out can help you scale you just can't carry as much product. I plan doing this locally when I have some time. There is a lot of goods that can be sold this way.
