Yes, you read that right; %15. It's a bug that uses the “” character. It's not a space character, it's a glyph named “Negative Acknowledge”, and it has a Unicode value of

U+0015

. This bug can literally delete most of the blocks in your projects. and here's how to do it:

1. Open the Scratch website and search up “%15”
   
2. We don't mind about the results, but just copy the character in the search bar (incase you forgot, it's “”)
   
3. Create a new project
   
4. Go to the sounds tab, and rename the sound to that character
   
5. Go back to the coding tab. You can now see that ALL but the motion, looks, and sound categories remain, but there is only one block in the sound tab
   

To make it even more insane, you can delete the sound tab as well. Here's how to do that.

1. In that same project, go to the costumes tab, and rename all of them to the character (incase you forgot, it's “”). Don't mind if it has two or more sprites and it becomes “”, “2”, “3”, … "n"
   
2. Go back to the coding tab. You can now see that the sound category is gone. Somehow, the looks category has four blocks.
   

Now you have successfully confused your teacher. Give yourself a pat on the back

this is (bug) = false
this is (hack) = yeaa
