This is a very simple solution based on vibration therapy. As per sketch there are two vibrational motor (cellphone vibrational motors) and these will run with batteries. These motors will create vibrations. Now what is needed is to just transfer these vibrations onto the tongue . When someone desires to take nicotine in any form (cigarette, tobacco) then just put this device on the tongue for 3 to 5 seconds and the result will be that the desire of taking of nicotine is no more.  Just use the device for 25 to 30 days continuously and the desire of taking tobacco will be ended permanently. The part of the device which is going to transfer the vibrations onto the tongue will be made with COPPER. The reason the device works is that it stimulates the neurones in the brain through tongue vibrations to suppress the desire of taking nicotine. I am presenting this solution as I have been able to quit tobacco addiction myself after using thi

There are products like battery operated bats available in the market to kill mosquitoes and insects but there is no battery-less innovation. My invention is very simple and very effective in killing mosquitoes as there is no need for recharging the battery of this mosquito bat. Only a bat and adhesive tape are required to build it. It will work to by trapping and killing mosquitoes. Salient features: (1) there is no need for recharging it. (2) the adhesive tape can be removed and replaced after use. (3) it is a very low cost design so anyone can afford it very easily. (4) it is safe and light weight (5) it can be used many times.

A new plate design could solve the problem of cake slices breaking and falling down. There is often a problem of serving cake slices after cutting a cake. A lot of cake is left behind on the plate at the time of serving cake slices. This problem could be solved with a?triangle shaped slicing template than slides down to cut and stays in place as each cake slice is removed and served.
