Easy Minion Lava Lamp and Film Canister Rocket

We've been making lots of fun Minion crafts today. What do you think of our lava lamp and rocket? These are easy to make and add a fun twist to the traditional lava lamp and film canister rocket. My artistic skills are not the best, so I'm sure you can do a much better job!

This lava lamp and film canister rocket are great for starting to think scientifically as well.

How to make a Minion lava lamp

A lava lamp is basically vegetable oil and coloured water in a container. You then add an Alka seltzer tablet ( or effervescent vitamin tablet ), which gives the bubbles.

These are reusable and perfect for science demonstrations, workshops and parties.

Read our full instructions for making a lava lamp here.

Investigation ideas

Try changing the amount of water and oil or use a half tablet ( or two ) and observe how the bubbles change )

Try to find a small object to float on each layer.

Questions to ask

What do you notice about the oil and water?

Why do you think the oil and water don't mix?

Where do you think the bubbles come from?

What do you think would happen if we used two tablets? Or, half a tablet?

What happens if you shake the Minion?

How to make a film canister rocket

For this, I just used a plastic film canister, you need the ones where the lid fits neatly on the inside not the outside.

Fill about 1-quarter full with water, add an effervescent vitamin tablet, replace the top and stand back.

Investigation ideas

Experiment using different amounts of water and effervescent vitamin tablets to see how changing one factor affects the time taken for the rocket to take off, its speed and the height it reaches.
