Hi everyone, Here I (Mr. Suhasa, Ph.D. student in Biotechnology, Bengaluru, Karnataka, India) have shown two available methods to cool the bottled drinks https://www.youtube.com/watch?v=cpVhJmma9g8&feature=youtu.be In another video of mine I have shown how to file a patent in India https://www.youtube.com/watch?v=tlQLWRhnblY&feature=youtu.be In another video of mine I have shown how to collect fallen or scattered coinshttps://www.youtube.com/watch?v=DAIyZ4y0CgM Also in another video of mine shown how to reuse old plastic bottles as tap - https://youtu.be/L79pTSoe3hs The said tap is user friendly and mainly applicable to remote areas, rural areas, and areas with poverty where water is stored in a bucket and people does not have access to tap. Use of tap also controls the flow of water and reduces wastage of water. I have also combined my videos telling two uses of read newspaper -https://youtu.be/CB86G3aeOSQ Watch how to make a broomstick using ONLY newspapers and adhesive tape -https://youtu.be/LOUqMIOV5d4 In my previous youtube video, 'Old newspaper broomstick,' I had used wooden handle for the broomstick made from old newspaper... Watch my old newspaper broomstick in action...https://www.youtube.com/watch?v=Tn5Nz3awE7U To know how to make it visit https://www.youtube.com/watch?v=P2CC86XfJ9M Also there is a video of mine that show how to make and apply natural lipstick or lip balm to heel cracked lips or cracked heels - https://www.youtube.com/watch?v=RmY8H0St9Z0 Also watch another video where I show an innovative use of old newspaper. The newspaper is conveniently crafted into dustbin to dump waste in it. This avoids the use of plastic cover to dump waste in it. https://www.youtube.com/watch?v=IKXUmt1Ie7I Also watch my video how to hold a bag with broken handle. A plastic bottle and its cap can be conveniently used to make a handle for carry bag -https://www.youtube.com/watch?v=gj9KTDBSFbs Like it...Share it...
