Lâmpada de Lava Caseira
Hint: You will need water, cooking oil, food coloring, and an effervescent tablet.
Oil floats on water because it is less dense, and effervescent tablets create gas bubbles that carry colored water to the top.

How these games are written
Four promises
🃏One screen runs it
Prompt, hint, clock, reveal, score. You never look down at a sheet while the hall waits.
📎A fact comes with its page
A fun fact is printed only when the page it was found on opens. Facts the door could not place were cut before you saw them.
🧩Riddles you may use
Traditional or written for this page. Nothing lifted from a book someone owns.
💡The hint costs a point
Answer without it and the team earns the bonus. The clock counts down the last five seconds out loud.
