One YouTube channel operator found a way to make marbles cooler.
According to Yoyomax12 – the diet free zone, here are the instructions:
Please read before making this craft:
** It is advised that you wear safety goggles and gloves when taking these out of the oven and putting them into the water.
** After baking/frying the marbles they may break if dropped onto a hard surface (like a tile floor). These are not suitable toys for young children.
** You may have broken marbles in the bowl of cold water. Drain the marbles in a colander, don’t stick your hands into the water to pick out the marbles.
1 cup marbles (quantity is up to you really) clear glass “cats eye” marbles work the best
pie plate (or other oven proof dish/pan)
Large bowl of ice water
Put your marbles into a pie plate and place the plate into a pre-heated 500 F oven for twenty minutes.
When I was a little girl I used to do this in a cast iron skillet over high heat on the stove (that’s where the “fried” part of “fried marbles” comes from). I find the oven method much safer. If you want to use a skillet there are instructions aplenty on the internet.
Prepare a large bowl of very cold water and add a few ice cubes.
Pour the heated marbles all at once into the cold water and wait a few minutes to allow marbles to cool enough to handle.
Drain, dry and enjoy!
