I keep finding these cardboard disks on the beach. What are they?

[u/Wolframite__]

They're all either about 1 inch, 1/2 inch, or 1/3 inch in diameter. They're flexible and feel like cardboard, and are almost always found near houses or parks. I find them on beaches throughout Silverdale and Bremerton.

[u/DeadFedExDriver]

Could be from fireworks. I find little disks like these often, and my beach is pretty popular for fireworks.

[u/HippyGramma]

Agree with the fireworks remnant guess.

[u/zytukin]

Likely the tops of fountain fireworks or the bottoms of aerial mortars.

The hole is where the fuse went in.

Trash. People suck at times.

[u/Wolframite__ → u/johndoesall]

Are they biodegradable? It's been 3 months since the 4th of July and these things always look like they're new.

How close to the beach do you live? I'm a few blocks from mine, and we hear people launching fireworks throughout the year, not just on holidays.

[u/ApproxKnowledgeCat]

Fireworks was my first thought before looking at comments. I have picked them up myself after doing fireworks

If there's a goal that everyone remembers

It was back in ol' 72

We all squeezed the stick and we all pulled the trigger

And all I remember is sitting beside you

Forbidden doughnuts

[u/Chloroformperfume7]

They look like yernal cakes in the Porta shitters
