Repeat as needed until all the Baking Packaging

Cut a small triangle in the center of a plastic cup’s base using a knife. The PLA Products triangle piece should be approximately the size of a small piece of candy and should be discarded. Repeat the procedure on a second cup.

Insert a headphone or ear bud into each triangle. If you look down into the cup, you should see the small speaker positioned in the center of the cup’s base.

Apply a liberal amount of tape to the back of the headphone or ear bud, which serves the dual purpose of holding the speaker in place and preventing any sound energy from escaping out of the triangular hole.

Turn another cup upside down on your work surface. Turn one of your speaker cups on its side and lay it on the base of the upturned cup.

Insert two pins through the speaker cup into the upturned cup’s base, thereby securing the cups together. The lower cup acts as a solid foundation for your homemade speakers and will also resonate a fraction of the sound energy projected from the speaker. Repeat this process with the second cup.

Place your cup supports side by side, aiming your homemade speaker cones in the direction you would like the sound to project. You might wish to label one speaker “Left” and the other “Right” to preserve the stereo sound experience.

How to Remove Price Sticker Residue From Plastic Cups

After you’ve removed the price tag or sticker from your new plastic cups, adhesive residue often remains. Gently rubbing your finger or fingernail over it does little to remove it, but several household products and oils will work to safely remove all the residue without damaging the cup. It may take several attempts or different products to remove all the sticky residue.

Soapy Water

Fill a sink with hot water and a squirt of liquid dish soap. Soak the plastic cup in the hot water for several hours or overnight.

Remove the cup from the water. Wipe away sticker adhesive with a sponge or cloth. Repeat as needed until all residue is removed.

Wash the plastic cup in the dishwasher or by hand when all sticker residue is removed to ensure all soap residue is completely removed prior to use.


Dip a cotton swab or dampen a cloth with baby oil, vegetable oil, olive oil, eucalyptus oil or tea tree oil.

Allow the oil to work into the sticker adhesive for 15 minutes.

Dip a soft cloth in warm, soapy water, and wipe away all oil and sticker residue. Repeat as needed until all the Baking Packaging sticker residue is gone.
