Abstract: An impact indicator includes a first tube having an outer dimension, a second tube having an inner dimension greater than the outer dimension of the first tube, and wherein at least a portion of the first tube is disposed within the second tube. A first fluid is disposed and held within the first tube via capillary action until a predetermined level of an acceleration event is received. A second fluid is disposed and held within the second tube via capillary action, and the second fluid is spaced apart from the first fluid by at least one plug. Responsive to receiving the predetermined level of the acceleration event, at least a portion of the first fluid exits the first tube and mixes into the second fluid to create a change in color of the second fluid to provide a visual indication of the acceleration event.
