Hint
Reveal a hint
Pop the colored balloons, then use the gas to create the last one.
Why It Works
The three colored balloons pop easily on the tack, but the pink one sets off a chain reaction through the boy. That gas inflates the last balloon, which you also bring to the tack. The trap is that the final balloon appears only after the pink one is popped.
