Build a Bridge from string, sticky tape and drinking straws
A great activity at home, or a class competition:
When the bridge is finished, it is tested by hanging weights from the middle to see how strong it is. It has failed once any part of the bridge gets below the level of the table-tops. (To remember this rule, it helps to imagine that the bridge is spanning a crocodile infested river!)
Some bridges can only just support their own weight, while others have supported 6 kg.
You might like to take a picture of your finished bridge, maybe while testing it, then you can email it to email@example.com
We will put the best entries onto our Facebook, Twitter pages etc. to show the world your fabulous design…
