00:00If you build a bridge with toilet paper and fold it 50 times in a row, it will break instantly
00:04when you step on it and send you falling into the abyss.
00:07You should know that the maximum weight a single sheet of toilet paper can hold is just one book.
00:11To support your weight with it, you need to fold at least 150 layers or more.
00:15It's better to build a wooden bridge with 9 pieces of wood.
00:18It will be much sturdier.
00:19It needs no piers and no nails to fix it.
00:21As long as you interlock and overlap the wooden sticks cleverly, a stable wooden bridge is done.
00:26You can stand on it steadily.
00:27It won't break no matter how you step on it.
00:29What's even more amazing is that three chopsticks can build a super load-bearing bridge.
00:34Now let's find out just how much weight it can hold.
00:43But the most impressive one has to be an ordinary A4 piece of paper.
00:47Lay it flat between two bricks, not to mention heavy objects.
00:50It can't even hold up half a brick, even if you fold it into strips to make it thicker.
00:54It still can't support half a brick.
00:56But once you fold this A4 paper into triangles and place it between the bricks,
01:00you'll be surprised to find that it can easily hold up half a brick.
