My Ping Pong Ball Stomp Cannon

This week my grandchildren are on half-term holiday so we will be getting visitors. I spotted one of the ping-pong ball stomp cannons on YouTube last year, liked it and then promptly forgot about it as I do with most things with my memory. Something triggered it in my mind again tonight and it should be just right for my grandsons to have a battle, especially if we make another one as a team effort. I cannot answer comments from people who have blocked replies, so if you don't get a reply to your question that may be the reason. It is probably worth reading my video description first because the answer may already be there. If you need a reply make sure your Google+ privacy settings allow replies from users that are not in your circles or add me to your circles first.

OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap. /user/GrandadIsAnOldMan
