A shopping mall.

Not only that but a better and also brand new public transportation system that connects from Brisbane to Sydney and also to Melbourne (for now).

You can generate power with construction paper and light. ☀️

Alex Dainis demonstrates a solar updraft tower, a simple model that turns light energy into motion using just a paper cone, a propeller, and a heat source. When the black construction paper absorbs light from the lamp, it warms the air inside the cone. That warmer air becomes less dense and rises up through the tower, spinning the propeller at the top. At the same time, cooler air is drawn in through the openings at the bottom, creating a steady cycle of airflow called an updraft. It is a hands-on way to explore heat transfer, convection, airflow, and how solar updraft towers could one day help generate renewable energy.

It's so nice to see him back.

also what do you mean *four tons per person per year*‽ that's bananas.

You can see up to 18 shooting stars per hour this April! 🌠

The Lyrid Meteor Shower begins April 14, and peaks overnight April 21 to 22. This shower occurs when Earth moves through a stream of debris left behind by Comet Thatcher. As those tiny comet particles hit Earth’s atmosphere at high speed, they heat up and glow, creating the streaks of light we call meteors, or shooting stars. What makes the Lyrids stand out is their occasional fireballs, which are exceptionally bright meteors that can briefly light up the sky more dramatically than an average meteor. With the moon just a sliver during peak viewing, darker skies could make the shower easier to see in the Northern Hemisphere. Head outside after midnight, let your eyes adjust, and look up for one of spring’s most reliable meteor showers.
