A YouTube video by creator deryatavas shows how to turn a used plastic beverage bottle into a jellyfish-shaped mood light using cuts, carefully shaped plastic and battery-operated LED string lights. The project’s precise cost, durability and safety under different build conditions have not been independently established; heating plastic can release harmful fumes.
A YouTube tutorial by creator deryatavas shows how to turn a discarded plastic drink bottle into a jellyfish-shaped mood lamp, using cut and curled plastic for tentacles and battery-operated LED string lights for illumination. Hunker reported on the project, which offers a decorative reuse idea, but its instructions involve heating plastic and require care because fumes may be harmful.
In the version described by Hunker, the maker removes the label from a taller, sturdier beverage bottle, washes it and cuts off the top. She turns the bottle’s bottom section upside down, marks out wavy tentacles and cuts the plastic into strips around the piece. The video shows her briefly passing a lighter flame over the strips to curl and reshape them. A hair dryer or heat gun is described as an alternative heat source. Rows of small holes can add texture to the tentacles.
The bottle’s top is also cut into narrow strips and heated so the plastic curls inward, forming a rounded dome. The maker then glues that section inside the inverted lower piece to create the jellyfish shape. Hunker describes an alternate arrangement: cut the bottom from the bottle and form the tentacles from the upper portion, then attach the rounded bottom as the dome. The project uses scissors or a knife, hot glue and a heat source; the report does not give a measured build time or a tested durability estimate.
To add light, the instructions call for making a hole at the top and threading battery-powered string lights through it. The wire can extend outside the lamp, with the battery pack remaining accessible, or the battery pack can be glued inside. The light strand can be folded to fit the tentacle length and secured inside with glue. Hunker also mentions small puck lights and solar LED lights as possible alternatives. It identifies LEDs as preferable to hotter bulbs because they produce less heat, though the report does not present product testing or electrical-safety certification.
A Decorative Use for Discarded Bottles
The project turns an everyday container into a small decorative light rather than sending it directly to disposal. Its appeal is practical as well as visual: the bottle supplies the lamp’s body, while battery-powered lights avoid the need to wire a fixture into a home’s electrical system. For readers looking for a craft project, the tutorial provides a way to make a distinctive, ocean-inspired shape from materials that may already be on hand.
That reuse is limited in scale. One craft lamp does not establish a broader reduction in plastic waste, and the source offers no estimate of how much material the project diverts or how long the lamp lasts. Cost claims also need context: Hunker says Dollar Tree sold a 10-foot LED string-light set for $1.50 per pack, but the report does not establish when or where that price applied, whether the product is still available, or the total cost of glue and other supplies. Readers should treat the listed price as a reported example, not a current universal cost.
The design also involves two distinct safety questions. Cutting plastic can leave sharp edges, and applying heat can release potentially harmful fumes, as Hunker warns. The lighting method matters too: the report recommends LEDs because they produce less heat than other bulbs, but users still need to follow the light manufacturer’s instructions and avoid placing an unsuitable or damaged light string against plastic.

How the Bottle Becomes a Jellyfish
Hunker’s report presents the lamp as a craft shown in a YouTube video by deryatavas, not as a commercially tested fixture or a new lighting product. The visual effect comes from altering a bottle’s shape: long cut strips form the tentacles, while a rounded piece creates the dome. A small strand of lights inside the plastic makes the finished object glow.
The instructions allow for changes in materials and arrangement. A sturdier, taller drink bottle is suggested, and paint pens or colored lights can add color. The battery pack may be left outside for access or placed inside, while the report also mentions solar LEDs for an outdoor decoration. Those are options described by Hunker; the source does not document tests of outdoor weather resistance, battery life or performance across different bottle plastics.
“LED bulbs produce less heat than other lights, and are the safest option to have touching the plastic bottle.”
— Hunker’s report on the DIY tutorial
Safety and Cost Are Not Tested
The Hunker account does not specify the bottle’s plastic type, the temperatures used, or whether the maker used a lighter, hair dryer or heat gun for each part of the demonstration. It warns that heating plastic can produce potentially harmful fumes and advises working in a well-ventilated area; it also suggests considering a mask designed to filter fumes. The report does not identify a specific mask rating or provide a formal safety assessment. The safest approach is to avoid inhaling fumes, keep heat away from flammable materials and use tools according to their instructions.
Other practical details remain unverified. The report does not state how long the lamp operates on its batteries, how securely the glued pieces hold over time, or whether its suggested outdoor version withstands rain and sunlight. It also does not confirm current availability or pricing for the cited string lights. The tutorial is a demonstration, not evidence that every bottle, adhesive and light combination will work equally well.
Follow the Tutorial With Care
Hunker’s report does not announce a product launch or a scheduled follow-up; it points readers to the creator’s existing video for the craft demonstration. Anyone attempting the project should check the instructions for their chosen lights, use battery-operated LEDs intended for the application, and keep the battery pack accessible if it needs regular replacement.
Because the method reshapes plastic with heat, readers should work outdoors or in a well-ventilated space, avoid breathing fumes and take care with flames, hot tools, knives and scissors. A hair dryer may offer a different way to warm the plastic, but it does not remove the need for ventilation or caution. The source gives no subsequent test results or updates, so questions about long-term use and outdoor suitability remain open.
Key Questions
What is the DIY lamp made from?
The Hunker-described version uses a plastic beverage bottle, hot glue and battery-operated LED string lights. Scissors or a knife and a heat source are used to shape the bottle.
How does the bottle get its jellyfish shape?
The bottle is cut into strips that become tentacles, then gently heated to curl them. A rounded piece of the bottle forms the dome. The creator joins the shaped sections with glue, according to Hunker’s account of the video.
Is it safe to melt or heat plastic for this project?
Hunker warns that heating plastic can release potentially harmful fumes. The report advises good ventilation and suggests considering a mask designed to filter fumes. Use caution around heat, keep it away from flammable materials and do not assume a particular tool or plastic type is risk-free.
What kind of lights does the tutorial use?
The instructions use battery-powered LED string lights, which Hunker says produce less heat than other lights. The report also mentions puck lights and solar LEDs as alternatives, but it does not provide independent testing of those setups.
How much does the jellyfish lamp cost to make?
The total cost is not confirmed. Hunker cited a 10-foot set of LED string lights sold at Dollar Tree for $1.50 per pack, but the report does not give a date or location for that price, confirm current availability, or include the cost of other supplies.
