The Bubble Machine works perfectly, and I won 2nd prize in the Thingiversity Engineering Challenge! Hooray!
Here’s the final video, which got very positive response:
Instructables.com accepted my Bicycle Bubble Machine for two contests, Summer Fun and Outdoor challenge. Actually, even if it’s not for winning, contests really seem to give you a good feel because of all the publicity, the nice comments and the constructive feedback (like: use a UV lamp and UV bubble fluid to produce bubbles that glow in the night! Now that will be cool!).
Update: Won a 1st prize in the Summer Fun Contest! A kid’s camper tent and a zip line kit — now I just have to find a place to mount it, as no tree in our garden meets the specs …
Life is beautiful 🙂
