What happens when lightningstrikes something that doesn't have a lightning rod or that is not grounded? Answered

Yeah the type explai a it all.

You have got to ask yourself why would lightning strike this object in the first place? Lightning isn't something that is out there looking for something to strike. It is a build-up of large voltage difference and it is looking for a way to equalise out this voltage difference as easily as possible. Hence it finds a "path of least resistance" down to earth. This is the idea behind lightning conductors. They provide this line of least resistance to 'encourage' the lightning to use it in preference to whatever else. So when lightning strikes a tree or even a building that hasn't got a lightning conductor it HAS found the easiest path to ground. Usually because it is wet. But, like the previous answerers have said this hot plasma stream will burn anything it comes into contact with. When things get struck by lightning it is often called "an act of god" (usually so that it can be excluded from insurance policies) which makes it all the more ironic that churches have to have lightning conductors.

like if you threw a big steel ball in the air? The lightning would hit the ball , keep going and look for the highest point near the ground (your hand).

It will tend not to strike nongrounded items. This is because it whats to make a connection to the ground. EX why: The ground becomes positively charged and the cloud negitive. a nongrounded item will not become negitivly charged easily so it will resist becoming a part of the path

In a miniscule fraction of a second it will find the lowest resistance path to Earth and once it finds it a small stream of plasma will develop which reduces the resistance further, allowing more current to flow which . . . until the full current of the lightning follows this path. You can't stop a potential difference of that magnitude having its way! That is one reason you shouldn't shelter under a tree in a thunderstorm. The lowest resistance path may not necessarily be through the tree - It may flash across from the trunk and find a better path through a nice salty human body.

How could it NOT be grounded? Is it floating? But yes, with a temperature of 60,000 degrees F I'm pretty sure the results wouldn't be pretty ;D.

Lightning almost always strikes objects which are grounded/have an opposite static charge/a lower static charge than the clouds.
I suppose the object would incinerate irrespective of it being grounded or not. :)
