First of all a clarification: "LEGO" is a trademark of the LEGO group in Billund, Denmark. This website is neither sponsored nor authorized nor supported by the LEGO group.
Back in the 1980's, I have been fascinated by the American space shuttles and their system of heat-resistant tiles. These tiles shall guarantee that the shuttles do not burn out during reentry in the earth atmosphere. After landing the tiles sometiles looked a bit baken.
Already some time ago I thought how to mock this process with LEGO bricks. Finally, I performed a small experiment with a yellow 4x12 plate, covered by transparent tiles of size 1x2 each.
Bad news first:
In a water bath in the microwave (almost) nothing happened.
The structure in the microwave oven.
The "LEGO sandwich" after several minutes with medium radiation.
Then I dust off an old flatiron and warmed it up.
Of course, the iron was not set diretly on the plate with the
tiles. Instead, I put an old white blanket in between.
