Table numbers floating in water

Hey girls, hoping someone can help

Somewhere I saw a picture of a short square vase filled with water with a laminated photo with a number attached floating in it. Or it might have just been a laminated number.

Anywho, has anyone seen this? I know it sounds simple but can't find it anywhere and want to do it DIY but wanted a pic.

Any input/ photos greatly desired.
TIA

This is all I can find for now. It's a great idea!
