Hey there! Flexible tanks are just like the bags you carry to school, except they are much larger and can hold liquids or gases. These bags are made of special materials that are strong enough to hold the liquids or gases without bursting or leaking.
Flexible tanks can be used for many different things, such as storing water for emergencies, transporting fuel to remote areas, or even holding chemicals for cleaning. They can be folded up and stored easily when they are not being used, which makes them really handy.
One great thing about flexible tanks is that they can be made in different sizes, depending on what you need them for. You can have a small one to hold just a few gallons, or a really big one that can hold thousands of gallons!
Overall, flexible tanks are just really useful bags that can hold different things and be made in different sizes. Just like the bags you carry to school, except way bigger and stronger!
