Lava is molten rock. It is still incredibly dense, if it wasn't burning hot you could walk on it. How would you plunge a whole arm in?
Very dense, yes, but stuff can be very dense and have low viscosity at the same time. Lava has a viscosity similar to peanut butter is what I've heard. You can push stuff down into it, it just requires some force to prevent the stuff from floating back to the top.
You could in principle walk on lava, either by moving quickly enough that you stay on top, or by protecting your legs enough that you could sink in maybe around knee deep where you would float.
I feel like you are challenging me.
Mercury is denser than steel, but Cody could still plunge his whole arm into a bathtub of it if he tried
Maybe it was very hot
