Bucket brigade

A bucket brigade or human chain is a method for transporting items where items are passed from one (relatively stationary) person to the next.

For the electronic delay line, see Bucket-brigade device. For the hacking method known as the bucket brigade attack, see Man-in-the-middle attack. For the non-profit environmental health and justice organization, see Louisiana Bucket Brigade.

The method was important in firefighting before the advent of hand-pumped fire engines, whereby firefighters would pass buckets to each other to extinguish a blaze. This technique is still common where using machines to move water, supplies, or other items would be impractical.

This method needs a number of participants sufficient for covering the distance.
