This forensic Serial Number Restoration kit utilizes the magnetic properties of steel to reveal obliterated serial numbers. This exercise includes a USB with a PowerPoint lecture and laboratory to assist in teaching this topic. Along with 16 steel samples (4 sets with 4 different numbers), the kit includes 8 rare earth magnets, 15 pieces of sand paper and four 2 ounce bottles of magnetic particle solution. The magnetic particle solution is 100% safe for school use which means it can be used without worries of acids or a fume hood. This kit is an excellent addition to your physics or chemistry lecture on the principals of magnetism. The combination of hands-on experience and forensics will get your students excited to learn about this topic.
