Yeast Starter Still Good?

Hello, I made a starter on Monday (today is Thursday), then on Wednesday I decanted the spent wort and added fresh wort to raise my yeast count/volume.

When I got up late last night for a bathroom run, I found the flask full of a bubbling mass and the sponge stopper cocked out of the flask and yeasty liquid running down the side and puddling on my dresser.

I put it in the sink, took out the stopper, and covered the top with sanitized aluminum foil. This morning it I found that it had run out more liquid and is still full of a bubbling foamy mass.

My main question is is this still viable? Could it have become infected from having the stopper cocked out of the flask? I'm assuming that the emission of pressure from the flask wouldn't have let anything in.

I'm guessing that the wort I added for my second iteration had too much sugar available and caused the problem.

Thanks in advance for any help on this.

Even if something got in, it will not be able to compete with your happy yeasties.
You should be fine.

Its fine... it likely went bonkers because there was simply a massive amount of yeast that was already in full gear.

Cool, thanks guys. Hopefully there's something left in the flask when I get home.
