What am I?
A spring for a spear gun trigger
A clip to attach a glove to a the end of a wetsuit sleeve
A nose clip
It is a nose clip. When you pull the two black rubber stoppers apart you can clip the spring over your nose to keep it tightly shut.
When a diver wears a full face mask (that is one that covers his whole face) he can not reach his nose to pinch it when he needs to stop his ears hurting from the effect of water pressure. So he wears a nose clip which keeps his nose shut so that he can blow into his nose to clear his ears underwater.

Amazing facts about…
Going Underwater
Water is colder than air. That’s why divers wear wet (or dry) suits to keep them warm underwater.
Everything looks fuzzy if you open your eyes underwater. That’s why divers wear masks to help them see clearly.
Water filters out colours. Red is the first colour to go. That’s why things tend to look blue underwater.
Sound travels 4-5 times faster underwater than in air. That makes it difficult to work out where the sound is coming from underwater.
When you go deeper your ears might hurt. That’s because the water above you presses on your ears. That’s why divers have to clear their ears by trying to blow through their noses while they hold their noses.
Even though diving equipment is heavy in air, it weighs much less underwater. That’s why divers wear weights to help them get their weight in water ‘just right’ – not too heavy and not too light.
There are currents underwater. A dive can swim out of quite calm water and suddenly find he or she is in a strong current.
There are also temperature differences underwater where warmer water and colder water are right next to each other. It can come as a complete surprise when a diver finds the water goes suddenly much colder (brrrr) or warmer (mmmm).
Remember things are very different underwater. So if you go diving, join a club and obey all the rules to make sure you are safe.
Then you will be sure to have a lot of fun.
