Wow... Never thought my little bro would end up getting the minikit for me.
I came accross him playing and I saw him just get the minikit on the ledge, I asked him "how the heck did you get on the ledge??" and he says that you use the force on those cans and you jump onto the middle one and just jump on them just as you get on them....
Never saw that coming, if someone else has a different solution they're still welcome to post it though.
