How to save the kid?

If a kid fell into a big metal urn,how to save him?
But i want to know how can he fell into a urn higher than him?The story in Chinese is the boy play on a small scale artificial hill and fell in.
So if the boy fell into a metal urn,what to do?Just let him dead?Or ask him  to backstroke?Or call superman for help?

• Give him a rope,wood,cystosepiment,live ring,ladder,net.With the help of them to float.Giving him a long straw to breath.
• Use something to blot up water.sponge,cotton, wadding,water pump,bailer水斗.
• Call for help.Call 999,ask help from passer by,ask a high man to jump into the urn and raise him.ask man ro drink all the water.
• Using machines to broke the urn.drilling holes,use cutting machine,use axe to break.

If it is a fact,i think the fastest way and best way is ask many people all together to push  the urn down.
