Try it out with the live demo, then follow the instructions in the project to add it to your project. NOTE: This project uses 3 sprites rather than 1 sprite with clones for simplicity sake, so new Scratchers can tinker with it easier. And also because using clones would remove from Scratch's 300 limit, which may be a bother for some users using this block.
This block allows to have an ask-block-like solution for asking for a user's age. Honestly, I don't know why anybody would use this, I just kind of made this because I was bored. But if anybody uses it, you don't need to give me credit.
