A portable lunch box with an attached LEGO base plate for building on-the-go.
Servings 1 portable building block lunch box makes

What you need

  • 1 metal lunch box (Hobby Lobby $6.99)
  • 1 LEGO Classic Green base plate (Toys R Us $7.99)
  • 1 package Scotch Removable Mounting Squares (Hobby Lobby $3.99)
  • 1 piece soft felt (craft store $.39)
  • Tacky glue
  • E6000 adhesive

Directions

  1. Measure the inside lid of the lunch box. Trim the base plate to about ¼" smaller than that measurement. This will allow the box to close. Make sure to test fit before securing!
  2. Attach 9 tape squares to the bottom of the base plate and press onto the lid.
  3. Trim a piece of felt to fit the bottom of the lunch box. This will help reduce the sound of the building blocks moving in the metal box. Attach with tacky glue and let dry.
  4. Using the remaining base plate, trim a piece to fit inside the lip of the lunch box base. You want to cover about half of the opening to make a little retaining wall for the building blocks. Attach with E6000, holding the piece in place until the glue sets.
  5. Allow everything to dry completely before filling with building blocks!
