STRAW SWIVEL | Urdu

This Straw Swivel can be made in less than a minute. You will require two bent straws – one thin and the other fat and a bit of tape. Take the fat straw, flatten its long end and seal it with tape. Trim the extra tape. Nip one corner of this taped end to make a small hole. Now place the short end of the fat yellow straw into the short end of the thin blue straw. The yellow straw should rotate freely in the blue straw. Now if you blow through the other end of the blue straw the yellow straw will rotate freely. Air will come out from the small hole in the yellow straw and give it a kick in the opposite direction to go round-and-round.
