Use a pointy object, reminiscent of a nail or a needle, to poke a gap by way of the middle of every can’s backside. Ensure the holes are massive sufficient to permit the string to cross by way of simply.
As soon as the holes are poked, take a chunk of string that’s about 20 ft lengthy. Thread the string by way of one of many holes within the backside of the primary can. Then, thread the string by way of the opening within the backside of the second can. Pull the string tight and tie a knot in the long run to safe it.
| # | Materials | Amount |
|---|---|---|
| 1 | Empty aluminum cans | 2 |
