Alex, this is a fantastic invention! How many times have you left the house and forgotten something you needed that day? Not a problem anymore with The Remember Scanner! I really think this invention would be extremely popular, imagine the security in knowing you would never forget your house keys again! I like the sound of how the invention works too, you just walk through it and if your all fine you just keep going, if you have forgotten something, beep beep! Great work, Alex, looking forward to seeing what you invent next!
