How Do You Build Bridges From Drinking Straws?
Children can learn about bridges by building models of them. They can build bridges out of materials such as balsa wood or even drinking straws. A simple challenge for kids, while creating their bridges, is to have them build a drinking straw bridge that can support some weight, such as a cup of pennies or some paper weights. Put four drinking straws side-by-side and attach them to each other using a three sewing pins throughout the length of the pin. If the sewing pins are not long enough to go through all four straws, remove one of the straws. Repeat this step one more time so that you have two sets of three to four drinking straws. Put the two sets of drinking straws side-by-side and insert three pins through the center straws. Try to get at least three or four of the straws in the middle hooked with the pins. To put the pins in, you’ll have to bend the outer straws out of the way; try to not bend them too much so that they don’t break. You should now have a bridge deck that is six
