Science4You: Gross Science


Enjoy Free Tracked UK Shipping on Orders Over £50!

We’re a small, family-run business — just me (Callum) and my sister, carefully packing every order by hand.

With a toddler keeping us on our toes and baby Theodore arriving on 14th July, life is a little hectic — but we’re truly grateful for your support.

Why buy from Lennie’s if dispatch takes 2–3 working days?

Because when you shop with us, you’re not just buying a toy — you’re supporting a UK family business that puts genuine care and love into every single parcel. 💛

When we ship, we use a Next Day service (1–2 working days), so most orders arrive within 3–5 working days from the time you place your order.

If everything in your basket has our SpeedyLlama badge, we’ll do our best to dispatch the same day — though we can’t guarantee it every time.

We might not be the fastest, but we’re honest, reliable, and always here to help if anything goes wrong — with free, no-fuss returns too.

Thanks for choosing heart over haste. 🧸✨

Exploring the less glamorous aspects of human biology can be both entertaining and educational for kids and adults alike. Here's a playful take on some of the "disgusting" science phenomena related to the human body:

  1. Gas and Flatulence: You can conduct experiments to understand why people produce gas and experience flatulence. Discuss the role of bacteria in the digestive system and how certain foods can lead to more gas production. You could even create a fun demonstration using balloons to represent the buildup of gas in the digestive tract.

  2. Digestive Process: Explore the journey of food through the digestive system. Simulate the process with household items to show how food is broken down, absorbed, and turned into waste.

  3. Poop Composition: Discuss the composition of stool and how it can vary in color, texture, and smell based on diet and health. Create a visual display using common materials to represent the different components of feces.

  4. Burping: Understand the science behind burping, which is another way the body expels gas. Experiment with carbonated drinks to observe how they can lead to burping due to trapped gas bubbles.

  5. Body Odor: Discuss the role of sweat and bacteria in causing body odor. Explore how different factors, such as diet and hygiene, can affect the intensity of body odor.

  6. Mucus and Snot: Investigate the purpose of mucus and its role in trapping and removing foreign particles from the respiratory system. You can create a simple experiment using colored water to simulate mucus's trapping mechanism.

  7. Earwax: Explore the science behind earwax production and its role in protecting the ear canal. Discuss the importance of proper ear hygiene and the risks of using cotton swabs.

  8. Gross Yet Important: Emphasize that while these bodily functions may seem "disgusting," they are essential for maintaining overall health and well-being.

By framing these topics as scientific investigations, you can make learning about the less pleasant aspects of the human body both informative and entertaining, fostering an understanding of how our bodies work and why these processes are important.
