It all started in 2004 when a tour operator asked my team to do research. as much as sediment worldFor example, a specialist in stony sediments left by water, wind and glaciers began to think about what kind of beach would be most suitable for building sandcastles. The study was conducted by comparing the sands of the 10 most popular beaches in Britain (at that time). While you can actually build castles on any beach,

If you want to build a real fort, it is better if your building is standing. And you need hard sand for that! The strength of sand depends on two factors: Grain characteristics of what they are made of and the water that allows them to bind to each other. The larger the grain angle, the better some of them are. However, the more elements stick to the grains of sand, the softer they become. This is why the microscopic parts of
shells It is a good choice for building castles. Finally, the finer the grain, the better it retains water. And the question of water is crucial in this case!

Or if you prefer, here’s the magic formula: Water = 0.125 x sand. But if you don’t have any science material, don’t panic! Just find a location in the sandy strip between the high tide line – easy to spot thanks to a set ofalgae And marine debris – and the tidal line. However, keep in mind that this area moves during the day, depending on the tides.

The following advice relates to the quality of the tools. In my experience, there is a direct relationship between the age of the hull, the size of the excavator, and the speed at which boredom begins. Adults find small excavators very frustrating and children like to use larger excavators but find them difficult to handle. So that the team atmosphere remains harmonious, so plan a large set of tools. The size and shape of the bucket is also important.
