A Rattle Cone - Idea for a simple paper noise-maker
Step 1: Roll a sheet of A4 paper into a cone (Narrow at one end and broad at the other)
Step 2: Fold the cone in half (Fold one end over onto the other end)
Step 3: Flatten the narrow end. This becomes the handle of the noisemaker.
Step 4: Now, gripping the flat handle (gripping it tightly near to the fold produces better results) , simply shake it back and forth and it should make a loudish popping/crackling sound as the rustle of the paper is magnified by the wide, open conical end of the noisemaker.
(Please could you tell me if this worked for you.)
