PERISCOPE
Imagine going to watch a match starring your favourite teams and then not being able to see it properly. This could well be the case if you are seated at an uncomfortable spot.
Instead of coming out of the stadium/field in a sour mood, carry your very own periscope to the next match.
A periscope is an optical instrument that comes handy to see things from an angle where it is otherwise difficult to see them. Like in submarines. People in submarines use a periscope to see objects above the ocean.
The things you need:
1. Two empty cornflake cartons
2. Two plain mirrors
3. Two pieces of cardboard
4. A pair of scissors
5. Packing tape
Step 1: Cut the tops from both the cartons.
Step 2: Place the cardboard to the bottom of both the cartons at a 45 degree angle and secure it tightly.
Step 3: Mount a mirror on each of the cardboard and secure it with the help of some tape.
Step 4: Cut out a one-inch square hole directly in front of the mirror in each of the cartons.
Step 5: Place the two cartons on top of each other - open ends together.
Make sure that the mirrors are placed at a 45 degree angle. Otherwise the periscope won't work!
