This is just a firework simulation. Just press the left key on your mouse (or tap on the touchpad) and fireworks pop! You can use this for your projects (if you can!) if you want fireworks in your game!
I made this by griffpatch's tutorial on youtube. If you want to be a professional scratcher but you are a beginner then I think griffpatch is the top priority. You can also see ShiftClickLearn and Zonx for games but I think that griffpatch is the #1 GO TO youtube channel. He is really good at explaining what the blocks do and why to use them, making the viewer actually understand then just copying what he's doing.
