Newspaper Tower
*
Predict how tall you can build a tower using
only two sheets of newspaper as building material. You can't use tape, glue, staples, or anything else, just two sheets of newspaper. You can...

Paper Bridge for Pennies
*
Using just a single sheet of paper (8.5 × 11 inches) and up to five paper clips, can you build a bridge that will span 20 cm and support the weight of 100 pennies? The area beneath the span must...

Holding Power of Nails
*
How strongly do different types of nails hold in wood? Try different diameters of nails, and try pounding them to different depths. To gauge the holding strength, measure how difficult it is to...

Strength of Glues
*
Try gluing wood together with different types of glue, e.g.: regular white glue, yellow wood glue, cyanoacrylate (super glue), and Liquid Nails. Glue a short piece (5–8 cm) to the center of a...

Strength of Different Construction Materials
*
There are many types of construction materials used for wood-frame houses. Compare the different uses for and strengths of different building materials, e.g.: particle board,
plywood, pine,...
