Have you ever bought a science kit, opened it up and found a list of extra stuff you have to go out and buy?

Not with Letterbox Lab, everything you need to do the experiments is in the boxes. Except water, we thought it was a bit much to send you water in the post.

Even the instruction booklets are bright, colourful and fun.

Your lab assistants Meg and Pico will guide your child through the experiments.

Don’t like written instructions? We video all of our experiments so you can see exactly what to do.

  • 5 star review  We received our first box today and I wasn't sure what to expect. My 6 year old absolutely loved it. Everything you need is provided, the instructions are easy to follow, the experiments are fun and the science behind them is explained in the book. I couldn't recommend this enough to anyone who has young children with an interest in science. Highly fun and educational. My little scientist can't wait for his next box. Thank you.

We are looking forward to opening the 2nd box next weekend..Great idea. Learning while having fun. Highly recommended these.

    5 star review  Our 7yo was so excited to get her first investigate box earlier this week. We dived right in and did the first experiment as soon as it arrived and it didn’t disappoint. This is only our first box but so far I’m really impressed with the quality of the materials as well as the content. Customer service has also been excellent.

  • 5 star review  Letterbox Lab is a fantastic educational product. I Home educate my 10 yr old son and we receive a new investigate box every month. Everything you need is supplied in the box, so no need to rush out and buy extra ingredients. Both myself and my son look forward to our science sessions every week, in fact it’s the highlight of our week. Always arrives on time and it does what it says on the box ‘ fits straight through your letterbox’ so no need to worry if we aren’t in on delivery day. This really is the best educational product I have bought my son. Thankyou Letterbox Lab �

    5 star review  Letterbox Lab is truly exceptional - my son absolutely loves it. We homeschool, and this is the best educational subscription box I've found. The experiments are so much fun, and there's a definite progression through each month's theme as you follow the experiments. This is a box that takes science education seriously and doesn't condescend to, or underestimate children's ability to understand scientific principles. My son has learned so much from Letterbox Lab - I couldn't be happier!

    5 star review  Received our first Letterbox Lab Investigate box today and its amazing. My boys loved it. Everything you need is included! Its definitely more expensive than other subscriptions but its worth it to have everything you need included. Our three boys aged 10, 7 and 5 have loved doing the first two experiments and we are saving the others for next week.
