| + | <br>3. You may have to add several layers of |
| + | cardboard inside. This lets the thermometer reach the inside of the can. It also adds |
| + | insulation. Try wrapping the cardboard with aluminum foil to reflect heat onto the can. |
| + | <br>4. Attach another reflector with tape. Puncture the reflectors with kabob sticks, and |
