When Dreamup Toys sent us these building toys that connect wooden train tracks to interlocking building blocks to review, I knew they'd be cool, but I had no idea they would supercharge my son's creativity so much!
Christmas gift: bundle a set of Hex bugs and LEGOs. This is a fantastic engineering challenge! There is a video in the post that shows how it works. My son is now working to figure out how to get his hexbug to go up a Lego ramp - hasn't perfected it yet, but it's a great project.
