Is it safe to use styrofoam for a floating surface portal

@nabokovfan87 has a photo of a plant corral made of styrofoam; it kept floating plants away from filter outflow.

I found the video of it! Added it to the Seachem Tidal Experiments:tm: thread 😂

I doubt it's safe long term.  Zenzo has a video when he was making his mudskipper tanks on some water safe foams (Islands and fully submerged) and the methods to do so. 

I would say... Cork wood is probably the "best" thing to use for something like that.

Suction cups + airline is the best way I've seen it with stuff available.  As well as the acrylic (or etsy) rings that people have around.

I cut the top off a single serve cereal cup. Made sure it was smooth and washed off any dust. My thinking is; if it's safe to eat out of for humans, it should be safe to float. I'd hope honey bunches of oats doesn't have toxins in their plastic cereal cups.

Edit: It is number 5 plastic which from what I researched seems aquarium safe
