Not paper or plastic

Plastic

If you use a plate, it has to hold at least a cup of water to allow it to float, and no paper plate. The paper plate will soak up the water.

@@handsonscience6713 it worked

Thank you! :)

There are no exact measurements. Measurements are determined based on the size you want it to be.

Thank you!! 😊

Thank you!! 😊

👍 Thank you for that suggestion! We will remember it when we create the automata 2.0!

thank you!! 😊

You could use a safety pin, but keep it closed. We don’t want you getting pricked/poked. You may need to place something between the popsicle stick and the safety pin so you can press it on and off of the battery.

Thank you!!! 😊

I think you said ... Very good, with this mechanism it is possible to make it with other animals! (yes, you are right! thanks!!!)

thank you! 😊

You can go to any hardware store

Yes it does need warm water!

@@handsonscience6713 woops

It takes Lithium 2032 coin size batteries which can be found at most stores that sell batteries

Hi! you can go to a store that sells different types of batteries. Look for ones that are Lithium Cell CR2023. Have Fun!!

I agree 100%!!

Thank you for changing it to "Like"!!! 😊

There aren't any specific size, you can make it any size you want it to be as long as you have the right pieces (pvc parts, pvc elbow parts, wooden boards, glue gun/glue stick, a screw, mat board, etc).

We appreciate the feedback! Thank you! 🤙

Have fun!

you could try the following - try using a wider tip dry-erase marker, sometimes if the tip is too thin it may come off stringy, place it in the water slowly, take your time, and remove it very slowly, draw a larger image. Give these a try! And, never give up!

@@handsonscience6713 ok great, thank you, we will try that :)

Thanks!!

Hmmm… didn’t think of doing that! We will try it!

Thanks!

Thank you for that explanation of what's happening!!

thank you! I'm glad you enjoy them!

Thank you!! The Hands On Science team appreciate your kind words!

Try it again, don't give up! Be sure to use dry erase markers (brand new works best), tap or luke warm water and pour slowly. Best colors to use are red and black.

I'm glad you enjoyed this video! We used 2-liter bottle w/cap, activated carbon, cotton balls, clean sand, clean gravel. Please let us know how yours turned out by tagging us on @hardwaresciencehi. Good Luck!

Because it's made from household items, it will work for at least 2-3xs. But, give it a try and see how many times you are able to use it! Let us know!

Thank you for that explanation on how it works!! 👍
