When the current restrictions were put in place, Sam added lots more ideas which can be done at home or in the garden. His site has now had tens of thousands of hits from more than 50 countries around the world.
It's been really useful for people who are stuck indoors during isolation.There are over 200 ideas that can come to you at the click of a button.
Sam has set up his generator so it chooses a suggestion from hundreds of activities - and if you don't like the first thing it comes up with, you can click again. Activities range from making a blanket fort (Sam's favourite) to playing board games, making slime, rock painting and the odd sneaky one, like tidying your bedroom.
People from all over the world have looked at it. We have a plug-in which shows where the hits are coming from. We've been looking up all those cities and towns and pinning them on a map. I think he's quite overhwelmed and really pleased.
The youngster who wants to be a scientist and an entrepreneur when he's older said the generator was initially made out of cardboard and glue before he gave it an upgrade and put it on the web.
I first invented it a few years ago when I was little. I used cardboard boxes, kitchen roll tubes, string and a stick and wrote the ideas on pieces of paper. You had to stir them with the stick, and then stick your hand in to take one out. Then when I was bored a few months ago, I decided to take it online.
Sam's had lots of people suggesting their own activity ideas for the generator, which he has added. He's also set up a directory of live streams and classes currently running plus one for days out, for when things get back to normal. In the future he says he'd love to turn his website into an app.
