So I'm working on a reveal for a logo. Its for a glass blowing studio. What I'm trying to do in the simplest way put is to take two lines parallel to eachother (will be a glass tube) and right in the center i want the two lines to expand into what would be a bubble or sphere which will end up bursting revealing the logo. I got the burst down etc I'm just not sure how to go about animating the expand. The tube will be spinning on a lathe while all this happens in animation. Please someone help me out here I've searched high and low on the net looking for something to point me that direction and have came up empty handed. Thanks a million in advance!!
