Add “Bubble Turbine Engines” to that dollar store glider.

I was going to do my “Science of Giant Bubbles” piece this week but found out about a bubble battle event this weekend.  Of course, I have never been to a bubble battle so my mind ran wild with the possible projects.  I went to the dollar store to pick up some supplies and my first idea turned out pretty well – the bubble plane.

If I’m going to be in a bubble battle… I mean if my son is going to be in a bubble battle, he will need Tactical Air Support.  So for 2 bucks I picked up a foam glider and taped fat straws on the ends to hopefully generate 2 jet streams of small bubbles. I cut slits into the straw ends so they would hold more solution though capillary action and hopefully keep the bubble effect going longer.  This is really the only tedious part – you’ll get better results with several narrow triangles cut into the end.

Well, that’s about it!!!  Before we got into the bubble solution, I made sure the plane could fly a nice straight glide.  It looks like it was designed to just loop so I just taped a Nickel to the front to get the balance right for a regular glide.

I dipped the back end of each straw into my bubble solution and let it go.  We got very nice streams of bubbles from the ends.  My son loved it and took over from there.  Getting a nice photo for this blog became the fun part but I lucked out with a few good shots.

It was the easiest of my ideas with a great “enjoyment” to “prep-time” ratio.  Next up: Bubble Bazooka


My mission through Daddy Engineer is to encourage people of all ages to enjoy engineering play.  Between work, kids and actually doing some of these projects, there’s little time left for blogging but I hope you enjoy my efforts.  Let me know what you think, your feedback and encouragement is much appreciated.
