Why can't we tickle ourselves?

-
The skin as a sense organ,perceives all kind of touch sensations as signals.These signals are sent to brain ,are interpreted and the body reacts accordingly.The brain can differentiate between the touch stimuli that we create ourselves and stimuli given by others .If we try to tickle ourselves ,our brain anticipates this type of touch from our hands and prepare itself for it.Since the element unexpectedness is missing ,the body does not respond the same way as it would if someone else were to tickle

CONVEX LENS Convex lens is thicker at the centre and thinner at the edges. An optical lens is generally made up of two spherical surfaces. If those surfaces are bent outwards, the lens is called a  biconvex lens  or simply convex lens. These type of lenses can converge a beam of light coming from outside and focus it to a point on the other side. This point is known as the focus and the distance between the centre of the lens to the focus is called the  focal length of convex lens.  However, if one of the surfaces is flat and the other convex, then it is called a  plano-convex lens. Difference between convex and concave lens: There is another type of lens known as concave lens. The major differences between the two are: CONVEX CONCAVE This lens converges a straight beam of light. This lens diverges a straight beam of light. This lens is thicker at the centre and gets thinner as we move towards the edges. This lens is thinner at the centre and gets thicke

wax fire

-
A  wax fire  is created when melted or boiling  wax  is doused in water.   In the case of wax melted down, only the top surface has access to oxygen, so the fire progresses slowly. When water is added to the wax, two things happen. Firstly, the water — being denser than wax — sinks to the bottom of the container. Secondly, as burning wax quickly reaches a temperature of well over 200 degrees C, the water instantly vapourises. When water changes from a liquid to a gas, there is more than a thousand-fold increase in volume. The water expands violently, and throws the hot wax layer above it into the air as small droplets. The wax now has a much bigger surface area exposed to oxygen so combustion takes place very quickly.
