Sebas Rockets 🚀

Welcome, rocket scientist! You just got your very own Sebas Rocket Kit! Follow these easy steps to build and launch your rocket. Let's go! 🌟

What's in Your Kit? 📦

Your kit comes with everything you need:

Item What It's For
🍼 Plastic bottle The rocket body — already filled with vinegar!
🥤 Vinegar (inside the bottle) Liquid fuel
🍪 Baking soda Powder fuel — when it mixes with vinegar… BOOM!
🥢 3 wooden sticks The rocket legs
🪢 Rubber band Holds the legs onto the bottle
🍷 Cork Seals the bottle so pressure builds up
🧻 Paper napkin For wrapping the baking soda

How Does It Work? 💥

When vinegar and baking soda mix together, they create a gas called carbon dioxide (CO₂). The gas builds up pressure inside the bottle until… POP! 💥 The cork shoots out and the rocket flies up into the sky!

Why does it fly?

It's the same idea real rockets use! Gas pushes down, and the rocket goes UP. Scientists call this Newton's Third Law: for every action, there is an equal and opposite reaction. 💡

Step-by-Step Instructions 🔨

Step 1 — Attach the Legs 1⃣

Place the 3 wooden sticks around the bottle and hold them in place with the rubber band. These are your rocket's landing legs!

Attaching the legs with a rubber band
Wrap the rubber band tight so the sticks don't move!

Step 2 — Add Baking Soda to the Napkin 2⃣

Open the paper napkin flat on a table. Pour the baking soda onto the center of the napkin.

Putting baking soda on the napkin
Put all the baking soda right in the middle.

Step 3 — Wrap It Up 3⃣

Fold and roll the napkin around the baking soda to make a little packet. Make sure it's small enough to fit through the bottle opening!

Wrapping the baking soda in the napkin
Roll it up nice and tight!

Step 4 — Load the Rocket 4⃣

Push the baking soda packet into the bottle and quickly seal it with the cork. The vinegar is already inside — don't shake it yet!

Loading the baking soda packet and corking the bottle
Push the cork in firmly so no gas escapes!

Step 5 — Launch! 5⃣

Now for the fun part!

  1. Shake the bottle so the vinegar soaks through the napkin
  2. Flip the rocket upside down (legs pointing up!)
  3. Place it on the ground with the cork facing down
  4. Step back and wait…

3… 2… 1… 💥 BLAST OFF!

Rocket ready for launch!
Stand back and watch it fly! :rocket:

Safety First! ⛑

Always build and launch with a grown-up!

  • ✅ Launch outside in an open area
  • ✅ Stand back after placing the rocket on the ground
  • ✅ Never point the rocket at people or animals
  • ✅ Wear old clothes — it can get messy and that's part of the fun!
