Putting Things in Order
Bubble sort is like bubbles rising in water - compare neighbours, swap if wrong order, biggest values "bubble up" to the end. Keep passing through until no swaps needed. Insertion sort is like sorting cards in your hand - pick each card and insert it into the correct position among the cards you've already sorted. Merge sort is like sorting by splitting a deck in half repeatedly, then merging back in order.
