Time for an Instructable that makes a noise! This Ballistic Bubbles Machine produces soap-bubbles that make a very funny and sometimes very loud crack when ignited. The bubbles contain a mixture of two gasses: Oxygen and Hydrogen.
The mixture of these two gasses is called… oxyhydrogen. In Dutch (and in German too, I believe), the word for oxyhydrogen is the brilliant noun “knalgas”, which can be translated literally as “crack-gas” or "boom-gas". This easy and cheap to build machine shows how appropriate the word knalgas is…
Also, watching the video might show the fun of making and using this machine…
If you're having trouble viewing the video from here, have a look at it on YouTube...
There’s a lot of pretty cool science happening in the Ballistic Bubble Machine. In step 7, some hidden secrets are revealed by using Red Cabbage Magik. The final steps of this I’ble will be about the bubble-science, if you’re curious.
If you’re not curious at all about the science but want to make a totally cool machine, read on! Build the machine and have fun with it. New years eve is so close! When you got all the stuff listed, building will take you about 4 hours, I think. (Lucky you, it took me a hell of a lot longer to figure it all out! This project has been haunting me for a year!)
Grand prize: An Instructables 3 months pro-membership gift-code from me.
Ricalvarez is the lucky winner! Congratulations!
Somewhere in this I’ble is a hidden reference to another, rather famous Instructable. The hidden clue is on one of the pictures in one of the steps. The first person who posts the location of the picture with the hidden clue, the name of the instructable that is referred to and it’s author is the winner. Scoochmaroo and members of a certain family living in the northern part of The Netherlands are excluded from this contest…
Step 1: Safety and an overview
BE CAREFUL, BE SAFE. READ THIS BEFORE PROCEEDING.
Oxyhydrogen / knalgas is an extremely flammable mixture of gasses. The gas will explode immediately when ignited. This Ballistic Bubbles Machine produces soap-bubbles filled with oxyhydrogen on a surface of water. When ignited, the bubbles will explode with a crack, but without much energy. The fact that the bubbles are small makes this apparatus safe to use.
So, in a nutshell:
- KEEP THE TIP OF THE TUBE ALWAYS UNDER WATER. ALWAYS!
- ONLY LIGHT THE BUBBLES.
NEVER (and I mean Never) LIGHT THE GAS
COMING OUT OF THE TUBE DIRECTLY!
- WEAR SAFETY GLASSES WHEN LIGHTING THE BUBBLES
Kids might enjoy the machine, but shouldn’t be allowed to play with it without an adult who is familiar with the machine and feels a responsibilty towards the kids being safe. Anyone operating the machine or being in close distance to it should wear safety glasses!
Understood? Sure? Did you see both pictures with this step?
Okay then, proceed to the next step and start building!
