I used an open styrofoam cup so i can skim the top of the surface of seafoam - not injesting the seafoam in gulps...

think of drinking REALLY hot coffee how you just sip a little coffee with a lot of air...

probably safer than pouring into the tube

Thats not a bad idea. Most people incorrectly just stick the vacuum tube into the liquid which is the absolute worst thing you can do.

Its arguable if sipping it in like you describe is safer then pouring it in. I’d think you can get more control over the amount of fluid going into the hose when you pour it in, but thats me.
