    Create your own alarm

    My son loved that he got to create an alarm for his door using the buzzing circuit so he knew when his brothers tried to come into his room. He liked that he could be creative with the project, and the magazine helped him think outside the box. It was a fun way to design a circuit and had a great end result!

    Use again and again

    My son thought this crate was interesting and challenging to put together in the best way. The project could be used multiple times after completion, with easy conversion between different uses. He's had a lot of fun learning Morse code as well as engaging in imaginary play with the different alarms he's created.

    Option for variation

    This crate had the option for many variations that were able to be created within this one crate. The game was a big hit and the trip wire trap was definitely my daughter's favorite. She had fun altering the circuit with the different ideas provided.

    Two projects to complete to keep my child engaged.

    I liked that there were two projects to complete. I think it provides an additional learning opportunity switching back and forth between the two projects and rewiring efficiently. My child has been really engaged, particularly with the trip wire, setting the device up around the house to surprise people. This crate has been a lot of fun.

    Very creative and I loved the trip-wire.

    The crate was extremely creative. I enjoy playing with the buzzing game. I absolutely loved the trip-wire. Every-single family member failed the test. The Morse coastal was fun too playing with my sisters.
