Even if you put such a powerful explosive as C4 inside your pillow, you could sleep peacefully for years.
But how is it that such a destructive weapon becomes a toy in human hands?
C4 explosive contains a powerful substance called RDX.
However, it is the plasticizers that make it soft, flexible, and relatively safe.
If something heavy falls on it, you step on it, or even shoot it, it won't explode.
It will only work if you use a special device that creates a powerful shock wave.
That's when it's time to cover your ears.
