This is a fun variation of the standard sand-timer used forever in science class. Blob timers provide an accurate way to time experiments with one drawback-you'll be so mesmerized watching the blobs of gel spiral their way down to the bottom that you'll forget to notice the time! Please note that colors may vary.
*Note the approximate time (2-3 minutes)
