User blog:Hyper Anon/Sleepover: Grace outruns an explosion

So there's this youtuber called Kavra, who makes edgy roblox stories.

So in this story, a girl named Grace is bullied and the squad turns against her. The bullies kill her boyfriend, she get mad, grabs a potion in science class, opens the classroom door and throws it, creating an explosion, but she manages to escape the school before the explosion can reach her.

The average should be 25 feet wide or 7.62 meters.

The average explosion should be from 2000-8000 m/s but let's say 8000 since the potion was made from science so thus it was enhanced and more powerful.

7.62/8000=0.0009525

The average school should be around 80 meters.

80-7.62 (assuming the classroom where she threw the potion in to doesn't count since she wasn't in the room.)
