For Father’s Day, my daughter picked out a Condiment Gun from Avon for me. I had never seen one before. It looks a bit like a ray gun and has two triggers – one for ketchup and one for mustard. When you open it up, there are two containers – each of which is compressed by a trigger.
I haven’t tried it out yet – but it looks pretty keen.
Here is a picture from the Avon.com web site - the Avon.ca site doesn't have it listed.
