Open-source roblox dev, (test)

Prompt

Act as an expert Lua programmer specializing in Roblox Studio. Write a Roblox script that makes parts rain down randomly within a 50x50 stud area. These parts need to spawn and drop with normal physics so they interact with the map and don't phase through it. Make the parts bouncy balls. They should stay for 10 seconds, disappear, and continue spawning in a loop. Also, make it so players can pick up these bouncy balls. When a player touches one, it should go straight into their inventory. For throwing the ball, the player needs to hold the right mouse button to see an arrow predicting where it will land, and then left-click to actually throw it. Make the thrown balls extremely destructive so they obliterate anything in their path. Lastly, tell me exactly how to set this up and test it in Studio.
