Timing system and device and method for making the same

A method of making a timing device comprising:

• a. forming a first reactive region on a first piece of tape;
• and
• b. forming a second reactive region on a second piece of tape, wherein at least one of the first piece of tape and the second piece of tape comprise an adhesive for securing the first reactive region and the second reactive region together and wherein securing the first reactive region and second reactive region together actuates the device to generate a detectable change within a duration of time.

A method of making a timing device comprising:

• a. forming alternating first reactive regions and second reactive regions on a piece of tape;
• and
• b. forming a securing means on the tape, wherein a section of the tape comprising at least one of the first reactive regions and at least one of the second reactive regions capable of being folded onto each other to actuate the device and to generate a detectable change within a duration of time.
