I can’t really be the only one who has wondered what it would be like to fall into Lava can I? Video Games have portrayed lava as a death trap ever since Mario made its debut on the NES. World of Warcraft has made extensive use of lava including the ability to hop across it in certain sections. As it turns out, hopping across lava might not be as ridiculous as it seems.
The article in question basically shows that when compared to water, lava is nearly 3x as dense and up to an order of magnitude more viscous. Because the average human has a density that is right around that of water, it would be nearly impossible to sink in lava. This is also why some people have a greater/lesser chance of floating. Not everyone has the same density and often times those individuals with greater percentages of fat can make themselves much more buoyant.
The article goes on to state that you can test this using a small figurine in a bucket of oil – however, in the name of science I’d be more than happy to feature a video of you or your family taking a trip to your friendly neighborhood volcano and attempting to hop across it just like you can in WoW.
