@just_day_by_day: A strange phenomenon in a tunnel that looks like a portal to other dimensions The tunnel is located near the Ituango Dam (Colombia). An air flow passes through it, the pressure difference (its periodic drop) creates standing waves of high and low pressure. The water in the air, for a moment at the moment of rarefaction, turns into saturated steam, which is what eyewitnesses see #tunnel #portals #strange
