Whether you're looking to create a cosy atmosphere or shake things up with a floating candle decoration, tealight candles are a popular choice. But do they float in water? The short answer is yes, and this is primarily due to their shape and size. Tealight candles are small and flat, which means they have a lower density than water, allowing them to displace more water than their own weight and stay afloat. However, there are some important steps to take before placing your candles in water, and there are also floating candles specifically designed for this purpose, which may be a better option for certain scenarios.

What You'll Learn
Tealight candles float due to their shape and size
Tealight candles are small and flat, which helps them float in water. The shape and size of the candle determine its buoyancy. The flat top and bottom of a tealight candle increase its surface area, allowing it to displace more water and remain buoyant. This is in accordance with the Archimedes Principle, which states that any object partially or fully submerged in a fluid will experience an upward buoyant force equal to the weight of the fluid it displaces. Since candle wax is less dense than water, it will always float.
Regular and floating tealight candles differ in shape. Regular tealights are flat and angular, while floating tealights have a rounded shape. The rounded top of a floating tealight candle helps protect the flame from water pooling on the surface. Floating candles are specifically designed to float and may be more stable in the water, but regular tealights can also float.
To ensure that a tealight candle floats properly, the wick tab at the bottom of the candle must be sealed with wax to protect it from moisture. Before placing the candle in water, hold it by the wick and gently lower it to avoid water flooding the top. It is also important to note that tealights should not be placed in large bodies of water with unpredictable currents, as this could cause safety issues.
Tealight candles can be floated with flowers in a bowl to create a beautiful centerpiece. They can also be used in floating candle bowls or as part of a centerpiece with other floating candles. When using tealights for decoration, it is important to be mindful of children and pets.

The density of candles is lower than water
The density of a candle is lower than that of water, which is why it floats. The concept of buoyancy dictates that an object's ability to float depends on its density relative to water. This means that even large objects can float if their average density is lower, as demonstrated by metal ships.
The density of candle wax ranges from 0.80 to 0.98, depending on the wax blend. In contrast, water has a density of approximately 1 gram per cubic centimetre (g/cm³). Since the density of wax is lower than that of water, a candle will float regardless of its size.
The shape and size of a tealight candle also contribute to its ability to float. Tealights are small and flat, which helps them displace enough water to stay buoyant. Floating candles, on the other hand, have a rounded shape that provides more surface area and protects the flame from water pooling on the surface.
Before placing a tealight candle in water, it is important to seal the wick tab with wax to protect it from moisture. Additionally, using a floating candle holder or choosing smaller tealights can help keep the candles stable and afloat.
Overall, the low density of candle wax, combined with the shape and size of tealights, allows them to float in water.

Candle holders can be used to display floating candles
Tealight candles can float in water due to their shape, size, and density. Floating candles are similar in size and shape to tealight candles but can be differentiated by their rounded tops and bottoms. The curved lip of a floating candle helps to keep it steadier and level in the water, giving it more buoyancy.
Before placing a tealight candle in water, it is important to seal the wick tab with wax to protect it from moisture. Floating candles can be placed in any container, as long as there is enough room for water around the candle. Containers can include bowls, vases, dishes, or mason jars. The container should be filled with water, and then candles are floated on top. It is recommended to give the candles room to breathe and move around, creating a better decorative piece.
To create a simple yet elegant display, floating candles can be decorated with accessories such as flower petals, leaves, or sprigs. These accessories can be chosen to match the season or event. For example, holly or fir sprigs can be used during the holiday season, while hydrangeas or roses may be more suitable for summer or weddings. Floating candles can be used both indoors and outdoors, adding a cosy and inviting atmosphere to any space.

Flowers can be used to decorate floating candles
Tealight candles float in water due to their shape, size, and density. Regular tealights can be used for floating, but they may be less stable and more prone to tilting or flooding than floating tealights, which have a rounded shape that provides more surface area and protects the flame from water pooling.
- Choose your flowers: Select flowers that complement your colour scheme and theme. You can use fresh or faux flowers, depending on your preference and the availability of fresh blooms.
- Prepare the flowers: Most flowers will naturally float to the surface of the water. To prevent this, use hot glue to affix the flowers to the bottom of your vase or container. Alternatively, if you're using decorative rocks or pebbles, you can anchor the flowers between the rocks for a secure hold.
- Add water: Fill your container with enough water to fully submerge the flowers and any other decorations you're using. Leave at least 3 inches (approximately 7.6 cm) of space above the water to allow the candles to float freely.
- Float the candles: Gently place your floating candles on top of the water. Be careful not to overcrowd the surface, as this can detract from the aesthetic appeal. Allow the candles to have room to move and bob gently.
- Light the candles: For the best effect, light the candles about 15-20 minutes before your guests arrive or before you plan to enjoy the display yourself. This will ensure that the candles are fully lit and creating a warm, inviting ambiance.
By combining the soft glow of floating candles with the beauty of flowers, you can create a captivating and romantic atmosphere that's sure to impress and delight your guests or enhance your own relaxation.

Floating candles can be purchased or made at home
Tealight candles do float in water, and you can purchase them or make them at home. The reason they float is due to their small size, flat shape, and low density, which helps them displace enough water to remain buoyant.
If you want to purchase floating candles, you can find them on Amazon, Etsy, or candle-making websites. However, be sure to buy candles specifically designed to float, as regular tealights may not be as stable and may tilt or burn unevenly.
You can also make floating candles at home with just a few materials. Here is a simple guide:
- Prepare your tart tins by pressing the metal tab of a candle wick into a glue dot while it is still on the roll. Repeat this process for as many candles as you want to make.
- Measure your desired amount of soy wax flakes, as this is a healthier alternative to paraffin wax. Place the wax into a melting pitcher and use the double boiler method to heat it gently.
- Once the wax is melted, remove the pitcher from the heat and stir slowly and often.
- Allow the wax to cool and settle for a few minutes, then add the wicks. Pre-waxed wicks are easier to insert and stand more firmly.
- The candles will take about two hours to harden completely. Once they are ready, carefully pull them out of the moulds.
- Fill a container with water and place your candles in it to see them float.
You can customise your floating candles by adding colour or fragrance. You can also place them in glass candle jars or lanterns to create elegant centrepieces for a dinner party or special occasion.
