Add a Tech Twist optional: You don't actually need a cell phone for this activity. Instead, you can substitute something with a similar size and weight (like a bar of soap).
Hints for uses in your library Activity Variations:
- For older participants, incorporate a way to propel the device across the water. Additional materials might be required.
- Conduct the activity at a school with a swimming pool. Have a teacher or activity leader “stranded” on a raft in the middle of the pool. The first team that gets their phone to the stranded person wins.

Troubleshooting:
-If your device doesn’t float, consider increasing the buoyancy by adding pockets of air or by distributing the weight over a larger area.
-Some participants might point out that it would be quicker to call for help yourself than to build a device to send a phone to a person stranded on a raft. Applaud their rationale and ask them to think of a reason why they would send a phone to the raft, and incorporate it into the fictional scenario.
