Is there a button or something?

So.  Not sure what went wrong here.  But I now have 35 sponges I was told were magic.

I’m not sure what to…is there a button? It didn’t come with instructions.  Drunk me’s eBay purchase has me baffled as to why I’d buy 35 of something I don’t understand.

I’ve basically been giving them away to anyone who walks near my desk.
