Based on the data table, which claim statement is correct?
The more air you put into the balloon, the farther it travels along the string.
The thicker the string, the farther a balloon can travel along it.
The air released from the balloon moves in the same direction as the balloon up the string.
The less air you put into the balloon, the farther it travels along the string.
