## プロパティ

- `Explosion.BlastPressure: float`：Used to determine the amount of force applied to Class.BasePart|BaseParts caught in the Explosion.BlastRadius.

- `Explosion.TimeScale: float`：Value between 0 and 1 that controls the speed of the particle effect.
- `Explosion.Visible: boolean`：This property determines whether or not the visual effect of an Explosion is shown or not.

## イベント
