Are you thinking of something like an art competition? that is one great idea during celebrations where you can pick 3-5 winners out of the art competition who have good artwork regardless of whether it's a bitcoin painting, bitcoin pizza or anything else that has a bitcoin main idea.
You can adjust how much the competition budget is for the winners regardless of whether you will give gift in the form of prizes or whatever you think is appropriate. The main idea is an art contest, yes it's about bitcoin. So I think with this idea kids and anyone who is aware of it will be wondering what bitcoin is and maybe you'll be an artist for a while in the community itself.
Thank you all for your various ideas, it really helped me a lot. @indah rezqi I will definitely try your idea out. I was able to get a total of how many children would be available today just 12 of them. And since most kids loves drawing I have decided on how today will go for them.
First, I wouldnt have to hire a dj just as some has suggested, because I do have a mini player and then I have organized with some of their moms to help me prepare a small dish that would cover for everyone. And I bought some drinks and then little gifts for them also.
Thank you all once again for your suggestions, it helped me a lot. I will be locking this thread now.
