Can paper be strong, as a bridge?
Take an ordinary piece of paper and place it on top of the two glasses. Let the children try to put something on top. Paper sag under the weight, and the bridge will break.
Prove that you do so now that the bridge will be made of paper so durable that it can pass even a car (of course, a toy). Fold the paper several times, so that it becomes like an accordion.
Now the bridge is ready to withstand the most difficult test!
Comment by Professor Nicolas: "We had a real engineering work. Bending a piece of paper accordion, we have created the so-called ribs that give the strength of the assembly, which allowed the bridge to withstand the weight of even a glass of water! It'S Great
Conducting an experiment with Professor at the amazing show of Professor Nicolas.
