Buy some Mylar paper ( a silver paper resembles the aluminum foil paper, which  is used for decoration etc.) Cut a small piece. Fold it thrice.  Make a spects shaped object using a  cardboard sheet and then hole it to view objects just like the glass portion of a spects. Paste or staple the three folded mylar paer into that hole. Then look through it a hundred watt lighted bulb from a distance. make sure that you can see only the filament of the 100 watt lighted bulb when looking through it. Now it is ok for eclipse watching.
   You can also watch the eclipse using two xray sheets, that dark portions of those pur together. Or you can reflect the sunlight on a white wall through a pinhole of a white paper.
