これは予想外！泡が一気に弾け飛んだ件

BoomBlastExplosion on Instagram: "Think of this as an unplanned experiment in combustion physics. In this incident, trapped fuel vapors mixed with air and reached the perfect ignition conditions—resulting in a rapid fireball expansion. No special effects. No movie tricks. Just chemistry, pressure, and timing. Explosions like this demonstrate how vapor concentration, ignition source, and confined space can instantly convert stored energy into force. It’s a powerful reminder of why ventilation, sy
