How Does Toy Boat With Candle Work?
What is a toy boat with candle?
A toy boat with candle is a classic children’s toy that has entertained kids for generations. It’s a small toy boat, usually made of tin or aluminum, that has a place to insert a candle. When the candle is lit, the heat makes the boat propel across water.
Toy boats with candles first emerged in the late 1800s during the Industrial Revolution. As manufacturing techniques advanced, it became possible to mass produce small, affordable toy boats. Adding a candle enabled the boats to be self-propelled, adding to the play value. Early toy boats were made of stamped tin and had simple pontoon or paddlewheel designs. Over time, the boats adopted more elaborate shapes like ships, submarines, and speedboats. Modern versions are often made of colorful, lightweight metals.
There are many variations of toy boats with candles. Some common types include:
- Pontoon boats – With two parallel floats connected by a platform
- Paddle wheel boats – Powered by a revolving paddle wheel
- Blow torch boats – Instead of a candle, a blow torch provides propulsion
- Pop-pop boats – Powered by a pressure-sensitive engine
- Submarines – With diving and surfacing capabilities
While designs vary, the classic toy boat with candle remains a favorite way for kids to explore engineering and have fun on the water.
How It Works
A toy boat with a candle utilizes basic scientific principles to move across water. The candle provides heat that melts a specialized wax at the back of the boat. As the wax melts, it runs down through channels to drip out an opening at the back of the boat. This provides a forward thrust that propels the boat forward across the water.
The key components are the candle and the wax. The candle is placed towards the front of the boat and securely housed under a structure. When lit, the flame provides heat that melts the wax towards the back of the boat. The melted wax drips out of an opening, providing a rearward thrust that pushes the boat forward.
The boat must be carefully balanced so that when the wax drips out, the boat remains level and buoyant. The melted wax coming out the back combined with the weight of the candle in the front enables smooth forward propulsion across the water’s surface as long as the candle remains lit.
Materials Used
Toy boats with candles are usually made from lightweight materials like balsa wood, cork, foam, or thin plastic for the hull. These materials allow the boat to float on water. The hulls are often hand-carved or molded into boat shapes like sailboats, speedboats, or paddle wheelers.
The candle is made of wax, typically paraffin or beeswax. Paraffin wax is a petroleum byproduct that is relatively inexpensive and easy to shape. Beeswax is a more natural option made by honey bees. The wicks are usually cotton string that soaks up melted wax via capillary action to fuel the flame. Wicks should be wide and stiff enough to stand upright while burning, but not so wide that they drown the flame with excess melted wax.
Assembling and Lighting the Candle Boat
Assembling a candle boat is a fun and easy project. Here are step-by-step instructions to put it together and light it safely:
Step 1: Gather your materials – you’ll need a wooden boat kit, candle, clay or putty, matches or a lighter. Make sure to have adult supervision if assembling as a child.
Step 2: Assemble the wooden boat pieces according to the kit instructions. Most kits are pre-cut and simply need to be slotted together without glue or nails.
Step 3: Once the boat is assembled, use a small lump of clay or putty to secure the candle upright and centrally on the boat. Press it firmly into place.
Step 4: Light the candle carefully using matches or a long lighter. Do this step with adult help to avoid burns. Make sure hair and sleeves are tied back.
Step 5: Once lit, place the boat in water such as a pool, tub, or lake. The heat of the candle will melt the putty slightly to adhere to the boat.
Be sure to keep a close eye on the lit candle and have water handy in case of fire. Enjoy this simple DIY boat with childhood wonder!
Tips for Best Performance
Here are some tips for getting the longest float times and best performance from your toy boat with candle:
Maximize float time by sealing any leaks in the boat with melted candle wax. Make sure the hull is completely water-tight. You can test for leaks by floating the unlit boat in water first.
Use smooth, calm water such as a small pool or bathtub for sailing. Avoid waves, currents, or wind which can tip over the boat.
Trim the wick to 1⁄4 inch before lighting for a cleaner, longer-lasting flame. Trim it with scissors or nail clippers. Maintain the wick by periodic trimming to prevent smoking or poor combustion.
Consider partially melting the bottom of the candle before inserting into the holder to help it stay in place. Remove any wax buildup in the holder so the candle fits snugly.
Avoid drafts, fans, or air currents in the room which can blow out the flame. Sail away from vents or open windows.
Troubleshooting
If your toy boat with candle is not floating or moving properly, there are a few common issues that may be causing problems.
Boat Not Floating
If your boat is sinking or not floating well, make sure that:
- The boat hull is sealed and has no leaks. Use caulk or glue if needed to seal any cracks or holes.
- The boat is properly balanced. Distribute weight evenly from bow to stern.
- You are using the right materials that float well, like balsa wood or Styrofoam.
Boat Not Moving Well
If your boat is floating but not gliding smoothly across the water, try these tips:
- Check that the candle is centered and upright. Recenter or relight if needed.
- Make sure the boat is balanced. The back should be slightly heavier than the front.
- Sand or smooth the bottom of the boat so there is less friction.
- Adjust the sail to catch more wind if sailing outdoors.
With some adjustments and troubleshooting, you can get your toy boat sailing smoothly again.
Safety considerations
When using a candle boat toy, it’s important to keep fire safety in mind. Small children should always have adult supervision when lighting candles or operating the toy boat. The candle flame is real fire and can pose a risk of burns or starting unintended fires if not handled properly.
Store the boat out of reach of small children when not in use. Extinguish the candle flame completely and allow melted wax to fully harden before storing the boat. Do not leave a lit candle boat unattended – adults should actively supervise the entire time the candle is burning.
Set up the toy boat only on a nonflammable surface away from flammable materials. Have a bowl of water or fire extinguishing materials ready in case the fire spreads. Teach children safe practices like keeping their hair and clothing away from the flame and blowing out the candle if it tips over.
While fun, the open flame makes this more of an interactive supervised activity than a regular child’s toy. Take all proper precautions and only allow children to operate it with adult guidance to avoid potential accidents.
Similar Toys
Candle boats aren’t the only self-propelled toys out there. Here are some other options to consider:
Wind-Up Boats
Wind-up boats use a mechanism that you twist to tighten an internal spring. As the spring unwinds, it powers propellers that make the boat move forward across water. Pros are that they provide longer run times and more consistent propulsive power compared to candle boats. Cons are that winding can be tricky for kids, and winding mechanisms can break more easily.
Solar Powered Boats
Instead of a candle, these boats have a solar cell that harnesses energy from the sun’s rays. This powers a small electric motor connected to a propeller. Pros are environmental friendliness and no open flames. Cons are reliance on sunny weather and higher costs than simpler boat designs.
Rubber Band Boats
Rubber band powered boats work by twisting the rubber band around the driveshaft to build up torque. Releasing the driveshaft makes the boat take off. Pros are simplicity and low cost. Cons are slower speeds and shorter run times compared to other self-propelled boats.
Overall, candle boats remain a classic toy because they’re easy to make at home yet provide enough power for exciting races across ponds and pools. The open flame adds visual drama too. Just be sure to take the proper safety precautions.
Fun Variations
A toy boat with candle offers lots of possibilities for creative fun and variations. Here are some ideas to inspire your inner craftsperson:
Make customized sails or flags for your boat using paper, fabric or even leaves and sticks. Let your imagination run wild with shapes and designs.
Decorate your boat with markers, stickers, glitter or other crafty materials. You can give it a name, racing stripes, artwork or anything else.
Host a themed boat race or regatta. Decide on a fun theme like pirates, ocean animals or your favorite book or movie. Dress up accordingly and decorate your boats.
Set up a race course in a pool, bath tub or other body of water. You can even divide the race course with buoys made from floating objects. Time the boats and award prizes.
Try making other objects that can float and be powered by a candle, like rafts, submarines or floating devices. Get creative imagining what you can make float.
The possibilities are endless when it comes to decorating your boat and coming up with fun themes and creative twists. Use your imagination and have a blast racing these classic floating candles.
