Making children love science is about turning theoretical rules into entertaining shows that come to life before their eyes. If you are looking for a science activity that is both practical to make and that children will admire for minutes, Colorful Floating Boat with Straws is a great option!
This toy boat, which moves forward leaving a fascinating color wave behind, offers an excellent visual material for children to understand the movement of liquids in preschool and primary school.
So, how can you prepare this magical boat course with materials at home? Here are all the details!
What is the Jet Engine Boat Experiment?
This experiment; It aims to observe the diffusion and thrust effect of the colored liquid released from the reservoir on an artificial boat designed using a lightweight material. As the colorful liquid floats into the water, it creates a stylish tail that resembles the smoke trail left by a jet plane in the air.
Required Materials
- Small piece of styrofoam foam (For boat hull)
- Small plastic or paper sauce container (For liquid reservoir)
- 1 bendable straw or thin plastic tube
- Food coloring or colored watercolor
- Water and a large bowl/basin
- Waterproof adhesive (hot glue) to fix the assembly
Try it Step by Step
- Design the Boat: Cut the Styrofoam foam into a boat shape with a pointed front, using a utility knife. A shape like the one in the video is ideal for buoyancy stability.
- Assemble the Motor System: Make a small hole in the bottom back of the plastic sauce container through which the straw can pass. Pass the straw through this hole and fix it with silicone to prevent water leakage. Position the long end of the straw facing the water from the back of the boat.
- Fix the Container: Stick this container evenly in the middle of your boat.
- Start Action: Fill your large container with clear water and drop your boat onto the surface of the water. Then pour the dense liquid you colored with food coloring (liquid soap or cologne can also be mixed to thicken it a little if desired) into the sauce bowl.
- Watch the Visual Feast: As the colored liquid drains from the straw into the water, it will disperse in the water, creating a wonderful swirl effect!
The Science Behind: Diffusion of Liquids
When explaining this experiment to your children, you can mention these two basic concepts:
Density Difference and Diffusion: The colored liquid we put in the container passes into the clear water below with the help of a pipette. Since the density, temperature or structure of the two liquids are different, the colored liquid does not disappear instantly in the water; As the molecules slowly mix together, they leave behind a wonderful flow trail like in the video. This is called diffusion in science.
Benefits of This Fun Try for Kids
- Visual Perception and Sense of Curiosity: Seeing how the color curves in the water increases children's aesthetic perception and the question "Why?" It triggers the ability to ask questions.
- Early Introduction to STEM: Children get a great analytical thinking practice by melting engineering (boat building) and chemistry (mixing of liquids) in one pot.
- Fine Motor Development: Assembling boat parts and moving liquids into small containers exercises small muscle groups.
Result: An Educational Color Festival
This jet engine boat experiment, which you can apply in science laboratories at schools, during bath time or in a large play basin at home, is the most colorful way to prove to children that science is not boring at all.
What colors do you plan to use in this experiment? How many centimeters did the mark left behind by your boat reach? Share your experiences with us in the comments!
