Try to build a bridge using only toothpicks and marshmallows. What if you don’t have toothpicks and/or marshmallows? Improvise! Use spaghetti and clay.
- small marshmallows
- two objects that are the same height
Set your objects 10”-12” apart. Start thinking about your bridge’s design. What shapes can you create with these materials that will hold a structure together to span the traverse between your objects? Try sketching your design on paper to see what it might look like. Does it look sturdy? Take out your marshmallows (try not to eat them all) and toothpicks and start building.
Then see if your structure can stay up. If it falls, try again.
What to try next:
There are plenty of challenges you can find online. Some set a limit to the number of toothpicks and marshmallows you can use. Others challenge the sturdability of your design by adding weight to the bridge to see how much it can hold. You can make the traverse even wider and see how your design holds up over a wider gap. Challenge your siblings, friends, and even parents. See who can build a bridge with the fewest toothpicks and marshmallows. See whose bridge can hold the most weight.
