The rope segments can be rearranged like a jigsaw puzzle and placed in the positions on the jumprope to form the following diagram:
As hinted by the flavor text mentioning "eleven-year-olds" and the eleven segments on each jump rope handle, the answer to each clue is eleven letters long, and they have been provided in alphabetical order by answer:
As the ropes indicate, copying the entries to the connected to the handles on the right, results in the following arrangement. Since there are a number of entries equal to the number of letters in each entry, reading down the diagonal spells an instruction:
M | U | S | T | A | R | D | S | E | E | D |
H | O | M | E | S | T | R | E | T | C | H |
N | E | V | E | R | E | N | D | I | N | G |
R | E | S | E | M | B | L | A | N | C | E |
N | O | N | S | U | R | G | I | C | A | L |
D | E | M | O | N | S | T | R | A | T | E |
A | Q | U | A | P | L | A | N | I | N | G |
W | A | V | E | L | E | N | G | T | H | S |
R | U | B | B | E | R | S | T | A | M | P |
D | I | C | H | R | O | M | A | T | I | C |
B | E | A | U | T | Y | Q | U | U | E | N |
The message MOVE US AGAIN instructs the solver to perform the same rearrangement of answers a second time. If needed, the answers can be rewritten on the left handles in this new order and then copied to the connected handles on the right:
D | E | M | O | N | S | T | R | A | T | E |
N | O | N | S | U | R | G | I | C | A | L |
A | Q | U | A | P | L | A | N | I | N | G |
R | U | B | B | E | R | S | T | A | M | P |
W | A | V | E | L | E | N | G | T | H | S |
N | E | V | E | R | E | N | D | I | N | G |
M | U | S | T | A | R | D | S | E | E | D |
B | E | A | U | T | Y | Q | U | E | E | N |
D | I | C | H | R | O | M | A | T | I | C |
R | E | S | E | M | B | L | A | N | C | E |
H | O | M | E | S | T | R | E | T | C | H |
Again reading down the diagonal provides the solution DOUBLE DUTCH.
