This ad is trying to sell beer by having the foam become a hockey player. Attractive ad to those hockey fans. The giant glass tipping over and pouring out the foam, the foam is undetailed enough that it could really be any fan in action. The giant glass is the ultimate selling feature "Bigger is Better". The nicely poured tap beer with the perfect head of foam. As it tips and the foam pours out it draws attention to the player that forms from the head, leading the fan to tend to want some of that.
This ad tends to make on thirsty for the refreshment advertised. It is as if I can put myself in this ad and the fan behind the scenes is wanting to buy this Coors Beer to at the least give it a try. Yes, i do think it is working to bring them in and making them buy it and try it.
