Does deuterium oxide (heavy water) taste sweet? If so, then why does it?
I'm curious, does deuterium oxide (heavy water) taste sweet? If so, then why does it?
Interesting question! Some people have reported that heavy water tastes slightly sweet, but it's not a widely shared experience. As for why it might taste sweet, some scientists speculate that it could be due to the slightly heavier water molecule affecting how taste receptors respond to it. However, this is just a hypothesis and not yet proven.
