A good pontoon landing isn’t about speed or strength. It’s about timing, wind awareness, and letting physics help.Turning head-to-wind at the last moment makes all the difference.

Dishwasher tablets look harmless – but they contain alkaline cleaners, enzymes, surfactants, fragrances, and often plastic film.
Safer for dishes ≠ safer for rivers.
Greener options? Powder, eco tablets, and using less.

Your breathing can become data. Using a @pascoscientific differential pressure sensor, students can see lung function in real time — pressure, airflow, graphs and interpretation all in one practical.

Same mass. Different shapes.Different terminal velocities. A 2 m water tube and a @pascoscientific rotation sensor make drag visible — then two umbrellas finish the argument.

Foiling on the Thames?
In theory – yes. In practice – shallow water, moorings, traffic and hidden hazards make it a risky business.
Some wide, quiet reaches might work for expert wind- or e-foilers… but the Thames really isn’t built for flying.

Some of the most important chemistry happens quietly.
Time-lapse and macro techniques reveal faint indicator changes and slow precipitate formation—turning “blink and you miss it” moments into powerful teaching tools.
