TIP: Adjust the speed and power settings for the
engraving to go a little less than halfway through the
⁄" acrylic. Use a strong magnet or tape to hold the
material firmly to the laser cutter bed.
After the first engrave and cut, carefully pick
out the part, flip it over, and re-insert it right back
into the material blank in the same position.
Laser it again, but this time only do the engraving.
(The Glowforge I used has a handy Ignore setting
to skip the re-cutting.) This will engrave the
ridges in the backside of the bubble ring as well.
Double the ridges, double the bubbles!
Fold a conventional paper airplane and
carefully insert the tip into the triangular T-slot
(Figure
B
). Slide it on until snug.
Dip the plastic part in soap solution and toss
for a bubbly flight (Figure
C
). Try throwing at
different speeds and arcs for best effect.
THANK YOU FOR FLYING AIR BUBBLE
I thought this would be a simple project, but it
required many revisions of sizes (Figure
D
), rib
layouts, and number of bubble loops (Figure
E
).
This “final” design is really just a starting point.
The symmetrical design can be modified or
simply scaled up or down: see what works best
for you. Good luck!
Rock crushes scissors, scissors cut
paper — but bubbles rule them all
