Design and build your own UFO model using recycled materials, decorate it creatively, then test simple flights to explore aerodynamics and teamwork.


Step-by-step guide to design your own UFO - World UFO Day
Step 1
Gather all the materials from the list and bring them to your building area.
Step 2
Clear a flat workspace so you have room to build and test your UFO.
Step 3
Decide team roles so each person has one job like designer builder tester or decorator.
Step 4
Sketch your UFO plan on paper showing the base the dome and where fins or weights will go.
Step 5
Measure and mark the size of the round base on your box or container.
Step 6
Cut out the round base from the box or container using scissors.
Step 7
Shape a dome using a plastic lid or folded paper to fit on top of the base.
Step 8
Attach the dome to the base with tape or glue until it is secure.
Step 9
Add fins or stabilizers by cutting small cardboard pieces and taping them to the sides.
Step 10
Place small weights under the center of the UFO to help it balance.
Step 11
Decorate your UFO with colouring materials stickers and creative designs.
Step 12
Set up a simple test area such as a clear hallway or a smooth ramp.
Step 13
Do a test flight by gently tossing sliding or rolling your UFO in the test area.
Step 14
Write down what you observed about how far it went how steady it flew and any tilting.
Step 15
Share your finished UFO creation and what you learned on DIY.org
Final steps
You're almost there! Complete all the steps, bring your creation to life, post it, and conquer the challenge!

Help!?
What can we use instead of a plastic lid, box, or small weights if we don't have them?
If you don't have a plastic lid use a paper bowl or folded paper for the dome, swap the box or container base for a stiff paper plate or recycled cereal box, and use coins or washers as small weights under the center.
Why does my UFO tilt or wobble when I test it, and how can I fix it?
If your UFO tilts during the test flight, rebalance it by checking the measured base, moving or adding small weights under the center, and securing loose fins or the dome with extra tape or glue.
How can I change the activity for younger or older kids?
For younger kids skip the cutting step by providing a pre-cut round base and let them focus on decorating with colouring materials and stickers, while older kids can sketch detailed plans, measure and mark the round base, cut their own parts, and add adjustable fins for testing.
How can we make the UFO more advanced or personalized after it's built?
Enhance your UFO by installing a small LED light inside the dome, trying different fin shapes and weight placements on the base to improve flight, and sharing photos and your written observations on DIY.org.

Facts about model building and aerodynamics for kids
âťď¸ Many UFO models can be built from recycled items like cardboard, old CDs, bottle caps, and yogurt lidsâsaving waste and sparking creativity.
âď¸ Even simple changes in shape (flat disc vs. dome vs. cone) change how air moves around a model and how well it glides.
đ¸ Flying saucer shapes became iconic after early 20th-century reports and make super-fun DIY models.
đ¤ Testing flights with teammates and tweaking designs together helps kids learn science faster and makes building more fun.
đ World UFO Day is a celebration that gets people looking up, sharing sky stories, and exploring curiosity about the unknown.
