Discovery Gateway is rolling out the welcome mat for Bob the Builder on May 17.

The cartoon character, who inspires kids to work together and take on challenges, will be the star of Bob the Builder—Project: Built It at the museum through Sept. 7.

The 2,000-square-foot multimedia exhibit will give kids a chance to flip through Bob’s construction blueprints and design their own, drive pint-sized building vehicles and even fit pipes together to fix a sink. Kids will also learn about sustainability, including solar panels and water conservation. 

And we’re going to send a family of four to the exhibit for free.

Your family can be among the first to experience the exhibit from 9 a.m.–11 a.m. on Saturday, May 17. This time slot is usually reserved for Discovery Gateway members only.

Enter to win the passes by leaving a comment below telling us about a project you built with your kid(s). Did you create a LEGO Star Wars Death Star with your son? Has your daughter discovered your Lincoln Logs collection? Did the kids assist in the construction of a tree house? Whatever it is, leave it in the comments below.

We will pick a winner early in the day on Friday, May 16.

Make sure to leave your email in the designated field or in the comment itself, so we can let you know if you won. The winner must respond with the names of everyone in his or her party to receive the passes, which will be available on Saturday at Discovery Gateway.
