Fill in the Wobble Bubble container to ½ with the Wobble
Bubble solution. Dip the tube into the solution, take it out and
let the excess of the solution drip back into the container. Hold
the tube horizontally and start blowing. The goal is to keep the
bubble from sinking down or rising up. The bubble
has to remain leveled up.
How
to reach this goal?
If the bubble is too light and rises up you should point the tube
slightly down. This way the solution from the tube will move onto
the bubble concentrating in its lowest point thus making the bubble
heavier. If the bubble is too heavy, point the tube slightly up
so that the bubble solution does not migrate onto the bubble.
The bottom line is that by leveling up the bubble and keeping
it horizontal you can blow a huge bubble.
The thickness of the bubble
membrane is essential for your success!You can determine the thickness
of the membrane by its color.Red shades indicate a thick membrane.
This means that the bubble doesnot need anymore solution. In fact,
you can even slightly lift up the bubble-blowing tube. Blue-Green
shades indicate a perfect thickness. Keep up the good job! If
the membrane is violet or white then we’ve got a thin membrane.
Tip the tube slightly down so that the solution can migrate onto
the bubble. While the solution slowly flows down you should make
sure that it gets evenly distributed along the surface and does
not accumulate on the bottom pulling the bubble down. What is
the trick here? The trick is to make the bubble spin. This way
the solution that by the force of gravity tends to gather on the
bottom of the bubble will gradually redistribute along the entire
surface. Keep it spinning!
Another good question:
How do we spin the bubble? If you blow into the center of the
bubble the air flow pushes the opposite wall and the bubble stretches.
If you blow at an angle (secant smaller than diameter) it creates
an additional force that rotates the bubble.
Tips
to Remember:
The bubble should not sink down or
rise up.
When it sinks - stop feeding it. When it rises - feed the bubble.
Shades of red equal thick membrane - stop feeding the bubble.
Blue-green indicates perfect thickness. Violet or white suggest
a thin membrane - start feeding the bubble.
Keep the bubble spinning!
To "feed the bubble" means to tip the tube slightly
down so that the solution migratesonto the bubble membrane.
To "stop feeding the bubble" means to point the tube
slightly up so that thesolution flow stops.
Do not blow fast when making the bubbles.
They will fly off the tube too early.
Move your hands, a fan, a paddle,
or a newspaper softly in the air around the bubble to make stunning
wobbling effects.
To catch a flying bubble gently
dock the tube to the bubble and start blowing bubble some more.
To make double bubble catch
a bubble with the tube at the angle and blow another bubble.
Blow bubbles together with a
friend by moving the tubes very close to each other.
