Snap Circuits

snap

Snap Circuits are fun. I got them for Christmas one year.
They are electronics. There is one where I take a red box and a speaker and I have to put them in a certain spot and it makes three different siren sounds.

I like to take the fan blade and the batteries and make it fly. Our cats get up close and I turn it on and then they jump up in the air. It’s really funny. They don’t get hurt.

There is a lightbulb and it’s so bright you can use it like a booklight.

If you have a little boy, maybe they should have them.

Baking Soda Explosion

sodaTo do this explosion, you need

1 tablespoon of vinegar

2 tablespoons of baking soda

soda-1

When you mix them together it overflows. I like it because it’s like a volcano.

You don’t have to do it in the basement but you at least have to do it in a big bowl otherwise it will make a huge mess.
