Why do sparklers stay lit underwater?

It might seem impossible, but yes—some sparklers can stay lit underwater! The secret lies in the ingredients. Sparklers are made with chemicals that include an oxidizer, such as potassium nitrate, which provides the oxygen needed for the sparkler to burn. Unlike a candle that needs oxygen from the air, sparklers carry their own oxygen inside the chemical mix. That’s why they can keep burning even when submerged.

However, not all sparklers behave this way. Standard wedding sparklers—like the ones from Wedding Day Sparklers—are designed for open-air use during events like grand exits or photo sessions. Underwater sparklers are a more scientific or specialty item, often used in demonstrations, not celebrations.

So while it’s a fun science fact, it’s best to keep your sparklers dry and safe. Want a show-stopping moment on land? That’s where Wedding Day Sparklers truly shine!

Stay bright, stay safe, and light up your moments the right way.

What are the boiling point and freezing point of a 0.743 m aqueous solution of any nonvolatile nonelectrolyte solute?

For a 0.743 m (molal) aqueous solution of a nonvolatile nonelectrolyte solute, the boiling point elevation and freezing point depression can be calculated using the formulas: ΔT_b = i * K_b * m and ΔT_f = i * K_f * m, where i is the van 't Hoff factor (which is 1 for nonelectrolytes), K_b for water is approximately 0.512 °C/m, and K_f is approximately 1.86 °C/m.

Using these values, the boiling point would be elevated by about 0.38 °C (0.512 °C/m * 0.743 m), resulting in a boiling point of approximately 100.38 °C. The freezing point would be depressed by about 1.38 °C (1.86 °C/m * 0.743 m), leading to a freezing point of approximately -1.38 °C.

Which would absorb more solar radiation if you assume that each covers an equal geographic area?

If two surfaces cover the same geographic area, the one with a darker color will absorb more solar radiation than a lighter-colored surface. Dark surfaces, such as asphalt, have a lower albedo, meaning they reflect less sunlight and absorb more heat. In contrast, lighter surfaces, like sand or snow, reflect a significant portion of incoming solar radiation, resulting in lower absorption. Therefore, the color and material properties of the surfaces significantly influence their ability to absorb solar radiation.
