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.
