Step 1: What to do if your straw is bendy

Trim about 1 centimeter (1/2 inch) off of the top tube.

Step 8: How to use

Blow into the bottom tube. If you made it right, you should feel your breath going up your nose. Sniff as soon as you stop blowing. YOU CAN SMELL YOUR OWN BREATH!!!

the whole smell your own breath thing seems entriely dubious, one sure fire way is to lick the back of your hand, if it smells bad so does your breath

I do it my pushing air out my mouth with my tongue while sniffing. It's totally dorky looking, but it works. The trick is in the face you make. Also, try flossing. You'll surely smell what others have been smelling if you don't.
It is not possible to smell your own breath. your mouth is so close/connected to your smell receptors that you are used to the smell and can't tell if its bad. the only time this changes is if your breath changes instantly (due to illness.....say, diabetic shock) or like if you burp up lunch.
