Hi Tuesday, how are you, I am fine and of course it is indestructible stuff day and today's stuff is a cyclone shelter.
In 1970 a devastating natural disaster struck the low lying country of Bangladesh the Bhola Cyclone, a powerful windstorm brought wind, rain and tidal surges causing flooding, flaring homes and farms.
When rebuilding they erected big,strong storm-proof buildings on legs to hide in until danger passes during future storms. So since 1970 Bangladesh has built thousands of super-strength shelters across the flat land near the cost.
A flat roof is an important design feature, it allows helicopters to land on it to deliver supplies or evacuate people. These shelters often look like big boxes on stilts.
