Marble Timer

My son absolutely LOVED this crate. He put it together with ease, and plays with it, daily. It is currently used more than our television. ? Well done, KiwiCo! 

This was an awesome crate for my daughter to explore STEM more. The addition of the dip dye wood art was really neat as well.

Exploring and being creative

My son loved this crate as much as his first and it was easy to assemble. However I had two problems with it... first, he was never able to get it to function properly as a timer. The marbles kept falling off the last arm before it went down enough to trigger the next marble. Second, the little foam piece at the bottom did NOT contain the marbles. He lost 3 of them in the first 10 minutes because they were falling all over the floor. I also wish the finished product could be stored somehow in the original box. 

Good but not great. 

My son, 8, usually loses interest in toys and such quickly. He has gone back to this marble timer day after day. I, mom, even find it fun and soothing. The sound of the marble running the track changes every time you adjust the wooden pieces, it is nice and melodic, he is usually shouting "come hear this one!". This was a great purchase and we are always pleased with Kiwico items. 

Plays with it day after day

This Marble Timer has been keeping my son so busy! He loved designing the board and seeing it come to life. Testing out the different speeds was fun!

Keeps him busy

This marble powered mechanism was so interesting as I saw my kid build it and keep changing the elements on the board to see how the time was affected. A really innovative way to bring in the topic of time.

Time is an interesting topic

Learning about mechanics and building was a great subject for my daughter to learn about. I saw her confidence shine as she was experimenting with the board pieces.

Love the subject

Exploring Mechanical engineering with this crate was an awesome way to incorporate STEAM into our homeschool routine.

Great for homeschool

The range of projects in this crate is awesome! I love how they all coincide and work together in the same theme!

Theme is great throughout

Thank you KiwiCo. This marble timer crate was a great family bonding experience between me and my daughter. She has learned so much in just one box.
