- Do you have to make a carrier that holds 6 cans – maybe you want to design yours to hold more…or to hold less?
- What are some different ways you can arrange the cans in your holder?
- Build Your Holder
- As you build, play with different materials to keep your cans in place.
- How can you design a holder that keeps your cans or bottles together and lets you easily remove one can at a time?
- Your holder needs to be easy to carry too. What handle will work best with your design?
- Test, Improve and Redesign
- When you’re done building your holder, it’s time test it out! Lift your carrier carefully, just a few inches above your table or desk. Ask yourself:
- Do the cans stay in place when you pick it up and move it?
- If your holder is bending or twisting, how can you reinforce your design?
- Think about what impact your carrier would have on wildlife.
- Are some of your materials better for the environment than others?
- If you could choose different materials, what would you pick?
- Make changes and try again!
