1 (Claim.
This invention relates to devices used with a
soap solution for blowing bubbles.
vIt is an object of the invention to provide a
bubble blower in which the pressure of the breath
of the user is controlled so as not to exceed that
which would rupture the ?lm of soap solution at
the ori?ce of the blower before the bubble is

of these apertures is to bleed o? some of the
pressure created by blowing into the tube so that
the ?lm of soapsolution covering the end Q will
not be ?exed so suddenly as to cause it to rupture
before the bubble is formed.
When the end d of the tube is dipped into a
solution of soap and water some of the solution
