Hope you all know the handpump, nothing from which we can get water , Before it was found everywhere now we can get it in some villages. Here I have a hand pump. Now let's make a hand pump with papaya steam . Now we are going to our Papaya Tree and Cut a green papaya stem between the leaf and the plant. Clean the steam and cut properly . Now we will cut the upper part. This will act like our valve in Hand Pump. Now have water in a bucket and updown the papaya steam see the water is coming out from the bucket like our hand pump. Now we wil discuss science behind this how water coming out. It is based on the principle of atmospheric pressure. When we push the steam down ward the valve open so water coming out but when we up the steam the valve closed so the air can't enter. Like this we can get water and alos our Papya steam pump works like our hand pump is up .
