How to play
下の角(はしが2つ重なった所)をしっかり持ち、うでを上から下へ、いきおいよくふりおろします。中の紙が飛び出して「パン!」と鳴ります。鳴ったら、出てきた紙を中にもどして、何回でもあそべます。耳のそばや、人の顔の近くではやらないでね。
Hold the bottom point tightly and swing your arm down hard. The inside paper pops out with a loud "BANG!" Push the paper back in and play again. Do not pop it near anyone's ears or face.
