Object of Curiosity

Urm, i think i've seen that 'red thing' before.But i just don't remember what is that and what is it for.

I wonder what can it be.

#1. a wounded finger cover

How to use it?

Yeah, the hole of that thing can fit your finger well. If your finger wounded and bleed like that, you can just put your finger in that hole. Its not as comfortable as you use the bandage, but at least this will stop the bleeding.hehe

Reason?

Just in case of there is no bandage around you when your finger is bleeding, You can just use this. I think its quite effective.

#2. As a whistle

How it works?

Take that thing and blow it in the hole just like whistle. Do not make your lips touch the thing or the sound will not be produced. The narrow hole make the air vibrate more and produce sound. 

Reason?

When you feel bored and do not have things to do, just take this and play with it. Its fun(I think). You can also use it to make some musics. Now you do not have to buy expensive music instruments if you have this.
