I. UNBREAKABLE BUBBLE
Materials required from kit: bubble tray, bubble
solution, long straw, round wand, star wand, wand
handle.
Materials required from home: an empty jar with a lid
(or a glass and a plate).
1. Clip the round wand onto one end of the longer of
the two wand handles, then clip the star wand onto the
other end. This will be the stand for your bubble.
2. Pour a little bubble solution into the jar, put the lid
on, and then shake the jar. This will coat the inside of
the jar with bubble solution.
3. Wet both ends of the stand, then place it in the jar,
with the star at the bottom, so that the circle wand is
not touching the sides of the jar.
4. Dip the end of the long straw into bubble solution
and carefully blow a bubble onto the round wand. The
bubble should be about 5 cm (2 inches) across and not
touching the sides of the jar.
5. Put the lid on the jar quickly.
Check your bubble every few minutes. How long did it
last? It might last for more than an hour. Why? Because
the air inside the jar is moist, which means the bubble
does not evaporate and burst.
H. BUBBLE GEOMETRY
Materials required from kit: bubble tray, cube framed
wand, pyramid framed wand, long straw.
Materials required from home: home made bubble
solution.
1. Pour bubble solution into the large cavity of the
bubble tray.
2. Holding the cube by its edges and place it into the
solution so that one face is submerged in solution. Roll
the cube onto another face. The first face should now
have a film of solution over it.
3. Keep rolling until each face has a film of solution.
Lift the cube out of the solution. What happens to the
films of solution? Amazingly, you should see films of
solution leading into the centre of the cube, where
there will be a small film.
4. Dip the end of the straw into the solution. Push the
end into the film at the centre of the cube and blow
gently. With luck, you’ll make a cube-shaped bubble at
the centre of the cube!
5. Repeat the activity with the pyramid. This time try
to make a pyramid-shaped bubble in the centre of the
shape.

Why do bubbles burst?
Sadly, bubbles don’t last forever! They
burst because the water they are made
from slowly evaporates. The water turns
to water vapour and mixes with the air.
As the water evaporates, the skin gets
thinner and thinner, until it breaks. In
dry, warm weather, evaporation is
quicker, so bubbles
don’t last long.
