popsicle stick chain reaction

video
This is the chain reaction
i made. It is 2 feet long and made out of 30 popsicle sticks.  My inspiration comes from that guy on america's got talent, Tim Fort. to trigger the chain reaction you pull out any stick, and the elastic force of the sticks blows the sticks apart. This could go on forever if you are good enough, but i just stopped there.
My record is 12 feet.(This uses no adhesive. The only thing required is popsicle sticks and 2 hands:) Video footage above.

popsicle stick bomb tutorial

you will need 5 ice pop (popsicle)  sticks . Optional: a rubber band

Take 3 sticks and wrap the rubber band around them. 

separate the 3 sticks like this.  i had to use 1 hand because i had to take a picture with the other, but please, use two. it's just easier. The top one has to be in the middle or else it won't work. 

take the 4th stick and force it in so it is under the side sticks and over the middle stick.

push the 5th stick in so it is over the side sticks and under the middle.

remove the rubber band.

walkalong gliding

Get this pattern at sciencetoymaker.org, click tumbleweing, print it out and tape it to phone book paper on the sides and ends. Rought cut it.

Now cut it on the lines. DO NOT CUT THE ENDS YET!!!!!!!!!

Fold up that end

now that end

fold up one side like that along dotted line up

fold the other side down

now cut the ends

cut the other end


To fly, hold it along the edge you folded UP, now with a slight flick, release it. If it turns, tilt the flaps a little bit in the directions it is turning. Now hold up the board (large cardboard box) and with a slight tilt launch and fly. for instructions see video.

popsicle crossbow damage test

can stick into paper from 10 feet

my VIKING catapult


This is my viking catapult, made out of kebab skewers, rubber bands, and a bottle cap. you can pretty much figure out how i made it using the picture. You pull back to fire. this thing can fire like 20- 30 feet (6-9 meters) depending on how you make it. The ammo is anything that can fit in the cap. Enjoy!

hey guys, if you could post more comments, i would appreciate that.


my water rocket launcher

this is a close up of the air valve

the water rocket launcher



This is the water rocket launcher i made out of 1/2 inch (1.25 cm) diameter PVC pipe, a BIC pen shaft, hot glue, a 1/2 inch (1.25 cm) tee, 2 end caps, duct tape, zip ties(used for bundling cables) a hose clamp, a 1 1/4 inch (3.175 cm) slip connector, string and 2 - 2 liter PLASTIC soda bottles. Don't use glass bottles for two reasons. First, it won't fit on the pipe. Second, the bottle goes very high, but a glass bottle has a lot of weight and it'll shatter, injuring someone. A plastic bottle doesn't hurt because an empty bottle has almost no mass. This can go like 50-100 ft (15-30.5 m) and even higher (10 times as high)if you add fins. I chose not to because if a finned bottle lands on someone it may injure someone because the fins give it mass. Thanks to slater harrison for the plans.

ice pop stick crossbow







This is an ice pop stick (called popsicle sticks in america) crossbow i made. I made it out of string , a clothespin, glue and obviously, ice pop sticks. The bolt or arrow is made of a wooden kebab skewer and tape. You pull the string back into the clothespin and place the bolt on the crossbow, as shown here in the 5th picture. Here are some pictures of me firing the crossbow. Oh, to fire the crossbow, you press the clothespin down. 3rd & 4th picture shows loaded crossbow. 2nd picture is the crossbow being fired. The arrow is in the air- it's the little blurry dash on the right. The 1st picture shows where the arrow landed. It landed on the far edge of my desk- towards my wall.
