Samuel stayed up until 1am on Friday and Saturday nights--and is still up at 11pm tonight--working on his portal gun.
He shaved down and shaped the Styrofoam shell, which he'll cover with paper mache, Bondo, and white paint. He also painted the barrel black, and added the central lighting core, which he built out of a clear acrylic plunger handle surrounded by a clear plastic tube. He'll light it with 22 tiny LED lights--11 orange, 11 blue.
He hopes to finish it in time for his Monster Mash party at school on Wednesday.
