Why should you never shake a test tube containing reagents by covering its mouth with a finger?

You should never shake a test tube containing reagents by covering its mouth with a finger because doing so can create pressure buildup within the test tube. This pressure can cause the test tube to explode, leading to potential injury from flying glass shards and exposure to hazardous chemicals. It is safer to use a stopper or cap to secure the test tube before shaking to prevent any accidents.
