Just sharing a little something I believed was pretty cool.
(Would've helped me solo blue buff as mid early on in the game.)
If you are a ranged champion, then this will work for you. Any ranged, it doesn't matter.
Stand here as shown in the picture (you may wish to clear the two lesser minions before attempting this as they are ranged.)
View image: Exploit BLue Buff
You will then be able to auto attack the blue buff, or use spells, whatever floats your boat, in order to kill the golem without taking any damage.
It will glitch out moving back and forth, however be warned, if you do not kill it fast enough it may begin to regen life etc.
This works well in ranked as when the other mid player sees you move towards your blue, he or his jungler may believe you are going to be low on HP, but with this trick, you can surprise them and possibly earn a gank for your team!
If people already knew this, I am just sharing what I know! So please keep the flaming to a minimum!
