Can you bleach fake hair

You can, only if you get heat resistant hair, the kind where you can curl it, or straighten it. BUT, nothing happened. I have blond hair, and I got brown/orange extensions, and soaked a piece of it in bleach, and absolutely nothing happened. It didn't melt, it didn't lighten, nothing. I started to let it soak at around 12:12, went to go work out, came back home at 3:20, nothing happened.
