Build a Magnetic Intruder Alarm

"Parents Keep Out!" With this magnetic intruder alarm, your child can explore magnetism and electrical circuits in a fun, hands-on way—no boring theory required.  For most children, science really clicks when they get to try things out for themselves and run their own little experiments.

Build the alarm yourself and discover how all the different parts work together to make it tick. Then put it to good use—keeping little siblings out of your room or protecting your secret snack stash.

This set is perfect for curious young minds who love technology and enjoy a good challenge. It’s also a great hands-on activity for children who need to see and feel things in action to make topics like technology, electrical circuits, and magnetism feel exciting and relevant.

• An exciting add-on to school science
• A fun holiday activity
• Helps develop logical thinking skills
• Can spark your child’s curiosity for building and hands-on projects 

The magnetic intruder alarm requires a Phillips screwdriver and two AAA batteries (not included).
