When I was a kid, more than once a got robbed by older boys. They stopped me and searched my pockets to see if I have any money they could "borrow".
Unfortunately, I did not wear a tie like some school boys do in UK.
Tie would have been a good place to hide my pocket money.
In this Instructable, I made a secret pocket in a tie.
You can keep money in it or even a bag of booze sneak into an event.

I opened the seams and sewed a zip on the back of the tie.
I used a blue zip as my tie was blue.
You can use the tie to keep money or even a bag of booze.
I used a bag from an ice candy together with a straw.
If you need a bigger bag, you can make your own with a heat sealer.
When you feel "thirsty", just pull out the straw and have a sip.
