I didn't cut it at all though, it did it itself. The whit has quit spreading and its huge and pinker then ever now? It's the craziest thing I've ever witnessed for sure. One thing I've noticed is that when I bought it, it came attached to a smaller rock and as now attached one of my much larger rocks. The hole appeared on the gap between the two rocks and as only stretched the gap so I just don't know. I'm gonna keep and a close eye on it for sure and watch how this goes. If worse come to worse and it starts melting or someone, I'll cut off a frag a rubber band it to a rock
