Homebrewing Soda, Safety Concerns

I wanted to try making my own soda this summer, and finally got around to it 10 days ago. Here's the thing. I didn't have/use any specialized equipment. I boiled water with sugar ~15 minutes, and combined it in 2-liter soda bottles with cool tapwater (dangerous?), flavor extracts and sucralose and let it get colder. Then added champagne yeast. Then stashed them in a dark cupboard. Today, I poured a little into a cup and it's fizzy and smells like it has a bit of alcohol, too.

But I know microbes can really mess things up and I just wanted to ask: Could the method I used be dangerous? Is there a risk of me having unintentionally grown a life-threatening bacteria, like the one that causes botulism? Thanks in advance.

This is way off topic, but is shows how much power an exploding 2 liter soda bottle can have. When in graduate school I knew some guys who made a cannon with one. They filled it partway full of liquid nitrogen (our physics lab had a lot) and put the cap on. They dropped it into a piece of pipe that was slightly larger than the bottle and was capped on one end, then dropped a length of 4x4 on top of it for ammunition. When the cannon went off the 4x4 went over the building next door and into a parking lot that they couldn't see. They were absolutely terrified that it had so much power and that they could have killed somebody with it that they never tried anything like that again.


I think what you made is safe, but there's no way to not produce alcohol with that method.
