Don't try this at home (if your home somehow has lava?). But this video shows what happens when you step in lava that's burning anywhere from 1292 to 2192 degrees Fahrenheit. You don't exactly sink in and become engulfed in the molten burning red liquid, you sink a little bit and then catch fire.
You know what's always amazing? Lava. The power of that liquid molten burning is stunning and out of this world—when you see it, you feel like you're getting a peek of hell. You know what's even more amazing? That people are making their own molten lava.
