Well, a spoon is designed to hold liquids and if it is has the mouth of the spoon bowl pointing up so that it CAN hold liquid is is the right side up (in terms of its use). Consequently if that is the right side up then if you turn it over it will be, by definition, up side down.
Yes. If you hold a spoon with the handle pointing straight down it's left side will look the same as it's right side. Therefore it is symmetrical.
It is upside down
Because the spoon is curved inward so your reflection appears to be upside down.+++For an explanation look up the principles of concave mirrors.
It is right side up.
When you look into the deep side a spoon, you appear to be upside down because the light particles that reach the spoon reflect in different angles, reversing the image inside. This happens because the spoon is not completely flat, and the curves create such an effect.
you go to the bathroom and flip the switch on the right
you press CTRL + ALT and the up, down, right, or left arrows.
Yes
Yes, we do in fact see things upside down until our brain turns it back around for us. You can prove this fact when you look at your self on the outside of a spoon, you will see yourself upside down! In fact our eyes see things the right way up but the image appears upside down in the retina, our brain works so fast that it can interpret the image quickly. +++ The spoon is no test of how sight works, but demonstrates a property of convex mirrors!
Look under the boot lid and you will find a plastic blanking plate just to the right of centre. Flip this plate out and insert key in the lock that is now exposed. Simple eh!
The spoon acts as a concave mirror at it's "loading surface". The idol of an object through a concave mirror which is further than the doubled focal length of it, is real, smaller and inverted (upside-down).
Pull the key out of the plastic remote. Look down in the crack, and you will see a gray little button. Press the button down with the key you pulled out, and flip the top plastic piece upwards while holding down the gray button. The battery will slide right out after that!
