Answer:
I am a portal to another world which you cannot enter. Only you can see me but I can't see you.
I can be sweet or sour. I do not rhyme with any other word
I stare at you, you stare at me.I have three eyes, yet can't see.Every time I blink, I give you commands.You do as you are told, with your feet and hands.What am I?
My snake-like body cracks and burns. I cause pain but pleasure too. What am I?
When I am caught, I am thrown away. When I escape, you itch all day. What am I?
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
