Step-by-step guide to make a plastic bottle guiro

What you need
Adult supervision required, empty plastic bottle cleaned and dry, permanent marker, sandpaper or nail file, scissors, wooden stick or wooden spoon for scraping

Step 1

Peel off the label from the bottle.

Step 2

Use scissors to cut off the bottle cap and neck.

Step 3

Use scissors to cut off the bottom of the bottle so you have a middle sleeve.

Step 4

Draw several parallel lines around the sleeve with the marker about one centimetre apart.

Step 5

Make shallow short cuts along each marked line with the scissors to form ridges without cutting all the way through.

Step 6

Rub the cut edges lightly with sandpaper or a nail file to smooth any sharp bits.

Step 7

Hold the plastic sleeve firmly in one hand keeping the ridged side facing out.

Step 8

Scrape a wooden stick or spoon across the ridges to make sound and listen to the rhythm.

Step 9

Try scraping at different speeds and angles to explore different tones and vibrations.

Step 10

Carefully deepen a few ridges slightly if you want a louder or sharper sound.

Step 11

Decorate your guiro with the marker if you want to personalize it.

Step 12

Share a photo or video of your finished guiro and what sounds you discovered on DIY.org.

Help!?

I don't have sandpaper or a nail file; what can I use to smooth the cut edges?

If you don't have sandpaper or a nail file, gently rub the cut edges (step 'Rub the cut edges lightly with sandpaper or a nail file to smooth any sharp bits') with the rough side of a kitchen sponge, a folded fine-grit emery board, or a strip of denim until smooth.

The guiro makes almost no sound — what troubleshooting steps should I try?

Ensure you made shallow short cuts along each marked line (step 'Make shallow short cuts along each marked line') without cutting through, then carefully deepen a few ridges (step 'Carefully deepen a few ridges slightly if you want a louder or sharper sound') and scrape firmly with the wooden stick or spoon at different speeds and angles while holding the sleeve steady (step 'Hold the plastic sleeve firmly').

How can I adapt this activity for different age groups?

For preschoolers have an adult do the scissor and sanding steps while the child draws the parallel lines and decorates (steps 'Draw several parallel lines...' and 'Decorate your guiro with the marker...'), for elementary-aged kids supervise as they cut shallow ridges and practise scraping (steps 'Make shallow short cuts...' and 'Scrape a wooden stick...'), and for older kids encourage experimenting with deeper ridges, different bottle sizes (step 'cut off the bottom of the bottle') and mounting the sleeve to a box for more resonance.

How can we enhance or personalize the guiro beyond the basic instructions?

To enhance and personalize your guiro, attach the sleeve to a small wooden box or empty tissue box to amplify the sound, try different scrapers like a comb or metal spoon to change tones, and decorate the sleeve with markers or stickers as in step 'Decorate your guiro with the marker'.

Facts about recycled musical instruments

♻️ Hundreds of billions of plastic bottles are sold worldwide each year, so upcycling bottles into instruments helps reduce waste.

🧰 A simple bottle guiro needs just a plastic bottle, a stick or spoon for scraping, and shallow ridges cut into the side.

🌱 Making instruments from trash is a fun hands-on way for kids to learn about music, science, and sustainability.

🎶 Scraping ridges produces vibrations that make sound — change the scrape speed or ridge spacing to alter rhythm and tone.

🥁 The güiro is a Latin American scraped percussion instrument traditionally made from a hollow gourd with parallel notches.

How do I make a guiro from a plastic bottle?

Start with a clean, dry plastic bottle. Mark parallel shallow ridges lengthwise with a marker. With an adult, carefully use a craft knife or strong scissors to scrape shallow grooves in the bottle wall — don’t puncture through. Smooth any rough edges with tape or sandpaper. Hold the bottle steady and scrape along the ridges with a wooden stick or spoon to create rhythmic sounds. Add rice or beads for a shaker effect if desired.

What materials do I need to make a plastic bottle guiro?

You’ll need a clean plastic bottle (water or soda), marker, craft knife or sturdy scissors, and a wooden stick or spoon for scraping. Optional items: sandpaper or a nail file to smooth edges, clear tape to cover sharp parts, dried rice or beads to add shaker sound, paint or stickers for decoration, and adult supervision and gloves for safety while cutting.

What ages is the plastic bottle guiro activity suitable for?

This activity suits preschoolers and school-age children with supervision. Ages 3–5 can decorate and play the finished guiro while an adult handles cutting. Ages 6–8 can help mark ridges and watch an adult cut; ages 9+ can cut shallow grooves with direct adult guidance. Always match tasks to a child’s fine-motor skills and supervise any use of sharp tools or small parts.

What are the benefits, safety tips, and variations for the plastic bottle guiro?

Making a guiro develops rhythm, listening skills, fine motor control, and creativity. Safety: always have an adult do cutting, cover sharp edges with tape, avoid small beads for children under three, and work in a well-lit area. Variations: try different bottle sizes, add rice for combined shaker/groove instruments, paint or wrap with fabric for visuals, or make several bottles with different ridge patterns to explore pitch and timbre.
