Steps in building a lolly stick arch bridge
Create an arched bridge of discarded lolly sticks. (ice cream lolly image by Renata Osinska from

An ice cold lolly on a hot summer day remains a classic part of the summer. Instead of tossing your lolly sticks into the garbage, repurpose them and build an arched bridge. Building a bridge from lolly sticks continues to be a common project often attempted in science class. Some classrooms even compete to build the lolly stick bridge that can hold the greatest weight without collapsing. This may sound complicated, but do not be discouraged. If you follow a few simple instructions you, too, can make a masterpiece of engineering out of your discarded summer treats.

Skill level:

Things you need

  • Lolly sticks
  • Wood glue
  • Spring clips

  1. 1

    Build the base of the bridge. Lay one lolly stick on the table. Put wood glue on half of the stick. Position the next lolly stick on top with half on the previous stick and half hanging off the previous stick. Put wood glue on half of the third stick and slide half of the third stick underneath the free half of the previous stick. Continue layering in this way until you have formed a line of lolly sticks the desired length of your arch bridge. Follow this same procedure to make a second line of lolly sticks the same length as the first line. Clamp the glued joints together with spring clamps and allow to dry overnight.

  2. 2

    Connect the two lines of lolly sticks by putting a dot of glue on opposing ends of one lolly stick. Place one end on one line of sticks and the other end on the second line of lolly sticks. At this point, the two lines of lolly sticks should be connected by a single lolly stick intersecting the parallel lines. Proceed to glue the necessary lolly sticks to the base of the bridge so the entire length of the lines of lolly sticks are connected by numerous intersecting sticks. It should like a lolly stick road. Clamp all of the glued joints and let dry overnight.

  3. 3

    Build the arch. Place a stick on the table. Put a dot of wood glue on one end. Angle a second stick up few centimetres and press it on top of the dot of glue. Continue laying lolly sticks and gluing them in an arch shape the same length as the wood road. Make a second arch using the same procedure. Put spring clamps on the glued joints and let dry overnight.

  4. 4

    Connect the two arches. Take a lolly stick and put a line of glue down the length of the stick. Press the entire stick against the centre stick of the arch. Do the same to the second arch. Put a dot of glue on both ends of a new lolly stick. Press one end gently against the stick that you just applied to the top of one of the arches and press the other end gently against the stick you applied to the second arch. Now one stick should be joining the two arches. Continue laying lolly sticks in this manner the entire length of both lolly sticks, about 14 sticks. Glue a stick to connect the two arches about 11 centimetres (4 13/32 inches) from the top, flat section of the arch. Continue connecting the two arches with lolly sticks and space them evenly over the entire arch. Let dry overnight.

  5. 5

    Finish your bridge. Put a dot of glue on the inside end-sticks of your two arches; a dot of glue should now be on four sticks. Place each glue-dotted end of the arch gently against the proper ends of the lolly road. The left ends of the arch connect to the left sides of the road and the right ends of the arch attach to the right sides of the road. Glue both ends of a lolly stick and gently press one end against the edge of the bottom road of the bridge and the other end against the top of the arch. Evenly space and attach the lolly sticks 3 centimetres (1 1/4 inches) apart the entire length of the bridge to connect the arch to the base and provide additional support. Let dry overnight.
