Can tasting a little bit of anti-frreze kill you?

Less than a drop is all you need to be able to decide if tastes sweet which tells you it's an antifreeze leak

. Less than a drop will not kill you. 

yes it can...........

No.  The sweetness taste buds are on the tip of the tongue so it takes very little to taste if it is sweet or not. Consider your body is mostly water. it is peeing in an olympic sized swimming pool.   Not noticed.

No. You'd have to drink lots of it.

If it could I would already be dead

SHORT ANSWER, NO, NOT A LITTLE BIT ON THE TIP OF YOUR FINGER. 

if youre not sure dont do it

No. Gulping it like a rat will. 

How big of a taste are you willing to gamble your life on ?

No.
