For this project, you need to have a Waterbomb base. I have a guide on it on my profile if you don't already know how to make one ；） ｅｎｊｏｙ！
First, take your Waterbomb base and arrange as shown
Fold the top most layer corner up to meet the top point
Repeat with each corner
Fold the two top most layers into the middle, like so
Repeat on the back
Now take the top most layers AGAIN and fold them down aligning the diagonal edge with the vertical edge like so. Repeat this on the back as well
Now take this flap you folded earlier, I find that if you rotate the paper 90 degrees it helps
Open up that flap
And put the flap inside, as shown
One done! Three more to go...
If you have no idea what I was doing from steps 8-11, here is a video to help
Step 12 complete
Now fold the top and bottom corners into the middle and repeat on the other side
Squash this down to make it 3D!!
Finished Waterbomb! I hope you enjoyed! Don't forget to comment, like an follow ;)
If you wanna put water in, there is a hole that allows you to fill it up! Also if its not going 3D then you can blow into this hole!
