Just press start and it will start to Lag. But press see inside to make it lag more.
If you want the best possible lag press see inside and press on the last sprite which has 13003 blocks. And make sure you start it while you do that. Thank you to: great_west who inspired me to do this. Also i will make this lag harder over the days and find new ways to lag scratch and make larger amounts of blocks in all the sprites to clean it up a bit more so i can make it lag more. A final thanks to everyone who supports me and helps me to make these things :)
