I went to the invention convention last week. My entry was Magneto hands free safety door. I even made a working model.

It was pretty neat. I put super strong magnets on the door with the same poles facing each other, so they will repel. That way, you can never close the door and kids room stays open and they don’t get their fingers caught in the door. That is the safety part.

On the other side of the door I also put a magnet with south pole facing out. Then using a ring with south pole exposed, I could push the door without touching it. That is the hands free part.

My entry got second prize at the invention convention; not bad!

I didn’t realize that one could also make a rube goldberg machine. I think that would have been a lot of fun. Oh well, may be next year!
