Ballast

Ballast is a heavy material added to boats or ships to help them stay steady and balanced in the water, similar to how adding weight to the bottom of a tall tower makes it less likely to tip over.

Examples

• When sailing on a boat, the captain carefully adjusts the ballast to ensure the vessel remains stable and doesn't tip over in rough waters.
• During our science class, we learned that engineers use ballast in trains to help keep the tracks level and prevent derailments when heavy freight cars pass by.
• In order to build a sturdy sandcastle at the beach, we decided to use wet sand as ballast, packing it tightly to keep the structure from collapsing under the weight of the waves.
