And the logical answer in our house, GHOSTBUSTERS! Matthew just LOVES the Ghostbusters movies. Matthew also just LOVES to make things with cardboard and tape. Ryan just LOVES Matthew, and LOVES all the things Matthew does. So what happens when you combine all those things?To think, all it took was two Portillo's boxes, a roll of brown tape from Uncle Chris, and two straws. They also made some accessories from Ghostbusters (not sure what they were), and apparently some modifications and repairs are being made tomorrow. But otherwise, it will keep these two entertained for hours!
