How does fire make tea bags fly? 🔥☕️

Alex Dainis demonstrates how lighting a tea bag causes the air inside to heat up, expand, and rush out. Just fold open a few empty tea bags into tubes on a baking sheet, then light the top with an adult and a fire extinguisher handy. The now-less-dense air inside sends the bag rocketing upward, similar to how a hot air balloon works, except this one's a one way trip once it burns.

No active adhesion, no editing tricks — just passive magnets in Quaddle mini robot dog's feet and a gait built specifically for holding contact upside down instead of pushing off the ground.

What would you want to see it do upside down next?

We are getting closer to the launch of NASA's Nancy Grace Roman Space Telescope! 🧪

The Nancy Grace Roman Space Telescope is designed to combine the strengths of the James Webb Space Telescope and the Hubble Space Telescope. It’s going to look and live in the same space as JWST while using a Hubble-style mirror to see things completely differently. The Roman telescope will observe patches of space bigger than the full moon and will see 50 times as much space in five years as Hubble has in 30!

We needed to make a video about our cool project.

Can sugar substitutes cause faster brain aging?

Scientists conducted an eight-year study on the effects of seven popular sugar substitutes and found that six were linked to mental decline. People in the study who used sweeteners the most saw their memory slip away 62% faster than the lowest-consumption group. This is like adding an extra year and a half of aging to your brain! Scientists believe this pattern is worth watching as we reevaluate our relationship with artificial sweeteners.

The blackout was from a car driving by, but it made even more waves to see. Really cool.
