步驟Procedures
1. 把反光紙摺成可以放進廁紙卷的三角柱體形狀。
1. Fold the reflective paper into a triangular cylinder which can be put into an empty toilet paper roll.
2. 把三角柱體插進廁紙卷中。
2. Insert the reflective paper into the roll.
3. 在黑色的紙張剪下一個大小與廁紙卷相約的圓形，並在中間開一個小孔。用膠水把它貼在廁紙卷的一端。
3. Cut a circle from a black paper and make a hole at the centre of it. Stick it across one end of the roll.
4. 把透明膠片放進廁紙卷的另一端。
4. Put a circular transparent film into the other end of the roll, just above the reflective paper.
5. 在膠片上放滿彩色珠子和釘。
5. Put some colourful beads and pins over the film.
6. 在珠子上貼上另一塊膠片。你已製成一個萬花筒！
6. Stick another film across the end of the roll. A DIY kaleidoscope is made!
把眼睛靠近萬花筒的目鏡，面向光線並觀察萬花筒內的珠子。
Hold the kaleidoscope up to one eye, face the light and look through it.
慢慢轉動萬花筒 — 你可以看到漂亮的圖案！Turn it slowly – you can view beautiful patterns through the kaleidoscope!
你也可發揮創意，為萬花筒進行裝飾！You can also decorate the kaleidoscope with your creativity!
