So I recently picked up minecraft after a long break at early 1.9 days. So after some TD fun i decided to see if an old bug worked and boi it does. Basically if there are 2 blocks ontop of eachoter and nothing above then you can break the top one and jump on the bottom one, it begins to spas you but if you jump again you get ontop of the second block. With this i did a this: climb halfway the ferris wheel. If this counts as exploit please let me know so i wont do it again
