These are fantastic!!! A lot of kids today are so bombarded with electronic things...but something retro like this is so much better...gives them a chance for some exercise...just be prepared for some noise...lol...and lots of laughter and enjoyment...I taught 1st gr. almost 40 yrs ago...I made some of these to use on the rainy days when they couldn't go outside to play...they loved them, but the teacher in the class downstairs below us wasn't real happy...lol...Naomi
